Detailed Solution

The simplified form of 3p(-p-a-r)-(-3p2 + 3pq + 3px) = -3ap-3pr-3pq-3px.
Given, 3p(-p-a-r)-(-3p2 + 3pq + 3px)
For the subtraction of two terms, the degree and variable of the terms should be the same.
So always subtract the like terms.
3p(-p-a-r)-(-3p2 + 3pq + 3px)
=-3p2-3ap-3pr + 3p2-3pq-3px)
=-3ap-3pr-3pq-3px
Hence, the correct answer is -3ap-3pr-3pq-3px
