Based on the provided options, the correct answer is Option 4: II and III.

Here`s a detailed reasoning for each option:

Option 1: I, II, and III

This option includes all three statements. However, statement I claims that India`s share in world trade will increase from 600 million US dollars to 5 billion US dollars by the year 2000 A.D. It`s important to note that the current date is already past the year 2000, so we cannot assess the accuracy of this claim. Therefore, Option 1 is not a valid choice.

Option 2: I and II

This option includes statements I and II. Let`s examine them individually:

I. India`s share in world trade is to go up from the present 600 million US dollars to 5 billion US dollars by the year 2000 A.D.

As mentioned earlier, the year 2000 has already passed, and without up-to-date information, we cannot determine the accuracy of this claim. Therefore, we cannot consider this statement as a benefit likely to accrue to India from the World Trade Organisation (WTO).

II. It will help boost exports of agricultural commodities from India.

This statement is plausible and aligns with the general objectives of the WTO. The WTO aims to promote global trade, eliminate trade barriers, and create a level playing field for all member countries. By participating in the WTO, India can benefit from reduced trade barriers, improved market access, and fairer trading rules, which can boost its exports of agricultural commodities. This can lead to increased revenue for Indian farmers and a positive impact on India`s agricultural sector.

Option 3: I and III

This option includes statements I and III. However, as mentioned earlier, statement I cannot be verified due to the outdated reference to the year 2000. Therefore, Option 3 is not a valid choice.

Option 4: II and III

This option includes statements II and III. Let`s assess them individually:

II. It will help boost exports of agricultural commodities from India.

As explained above, participation in the WTO can facilitate increased exports of agricultural commodities from India. By engaging in negotiations, trade agreements, and dispute settlements within the WTO framework, India can benefit from a more favorable trading environment and improved market access for its agricultural products.

III. India`s share in world trade is likely to triple by the year 2000 A.D.

Similarly to statement I, this claim cannot be evaluated accurately since the year 2000 has already passed. However, considering India`s growing economy and potential for international trade, it is plausible that its share in world trade could have significantly increased over time.

In conclusion, Option 4 (II and III) is the most reasonable choice based on the provided statements. The World Trade Organisation can potentially assist India in boosting its exports of agricultural commodities and increasing its share in world trade.
