Let's start with coefficient.
Note that 11³ = 1331 and 12³ = 1728
and (-11)³ = -1331 and (-12)³ = -1728
So -1452 and 1452 cannot be perfect cube.
We are left with B or C.
Now check for exponent of p.
p²¹ has exponent multiple of 3 which makes it perfect cube
The exponent of p²² is not multiple of 3 so it's not perfect cube.
So final answer: B) -1331 m¹⁸ n¹⁵ p²¹
