1) m has more than 9 possible factors
2) m is a multiple of p^3

Can somebody explain in detail the answer?

Consider :
2) m is a multiple of p^3

So,
m =>p^3*t*X

t- it is mentioned that t is a factor
X -in case there are more factors , please note , I have not considered option 1 yet
solving further..

m=>(p^2*t)(p*X)
so , m is a multiple of p^2 t

I guess answer is B.

OA is B.
