**(d)**

Here,

The gravitational force on mass at due to mass

at is along

The gravitational force on mass at due to mass

at is along

The gravitational force on mass at due to mass

at is along

Resolve forces and into two rectangular components

and are equal in magnitude of equal and opposite direction
