The correct answer is Option-2 i.e., Investor 1 has made the best investment. Here is why:

Option-1 suggests that Investor 2 made the best investment. But if you consider investor 2`s portfolio which is highly weighed towards Scrip A and D. Despite some gains, Scrip A and D also have severe drops that will greatly affect the performance.

Option-3 contends that Investor 2 suffered a net loss during the year. To conclude this one needs to do intricate calculations about net gain or loss for every investor.

Option-4 states that Investor 3 suffered a net loss during the year. This too, requires thorough calculations to affirm.

Now, if we look at the correct option, Option-2, implying that Investor 1 has made the best investment. It is highly probable because Investor 1 has the largest amount of his investment in Scrip D, which has performed significantly with substantial gains of 20% and 30% in different quarters of the year. This led to his portfolio outperforming the others and thus, he has made the best investment.
