Question

Fill in blank (93):

• A. at
• B. on
• C. above
• D. over

Answer 1

The correct option is A at

Option A: 'At' indicates 'a point or place occupied in space'. The meaning is relevant here: the satellites are occupied in different points (heights) in space (the atmosphere).

Hence option A is correct.

Option B: 'On' refers to the top or surface of something.

Options C and D: 'Above' refers to a higher place or position.

Similarly, 'over' means 'above in place or position'.

These words mean 'being literally on top of heights', but the meaning formed leaves the sentence incomplete. In comparison, 'at' is the most suitable option as it simply means that the satellites should be placed in different points in space.

Hence options B, C and D are incorrect.
