The correct answer is option 3. The statement that NIIF and NIF (National Investment Fund) are the names of the same organization is not correct.

Now let`s look at each option to understand them better:

Option 1 states that the creation of National Investment and Infrastructure Fund (NIIF) was announced in the Union Budget, 2015-16. This is correct as the announcement for the creation of NIIF was indeed made in the Union Budget of that year.

Option 2 states that NIIF is a fund for enhancing infrastructure facility in the country. This is also correct as the main purpose of NIIF is to finance infrastructure projects in India.

Option 3, as mentioned earlier, is not correct. NIIF and NIF are not the same organization. NIIF stands for National Investment and Infrastructure Fund, whereas NIF stands for National Investment Fund. These are two separate entities.

Option 4 states that NIIF can have more than one alternative investment fund. This is correct as NIIF is a fund of funds and can invest in multiple alternative investment funds.

In conclusion, option 3 is the correct answer as NIIF and NIF are not the same organization.
