The question provided a map with four marked locations and a list of four space organisation units. It asked to match the numbered locations to the units on the list. The correct answer is Option 4.

Let`s break down each option:

Option 1: This suggests that ISRO (A) is in location 4, IIRS (B) in location 1, NRSA (C) in location 2, and SAC (D) in location 3.

Option 2 and 3: Both these options are identical and suggest ISRO (A) to be in location 1, IIRS (B) in location 4, NRSA (C) in location 3, and SAC (D) in location 2. This is the same placement as the previous option, meaning they`re equally incorrect.

Option 4: This option suggests that ISRO (A) is in location 4, IIRS (B) in location 1, NRSA (C) in location 3, and SAC (D) in location 2. This option changes the placement of NRSA(C) and SAC(D) in comparison to the previous options, which is the correct placement according to the given map.

In conclusion, the correct answer is
