a) –2n + 9m – 17p

b) –2n – 9mn + 17np

c) –2n + 9mn – 17np

d) –18n + 81mn – 153np

The correct answer is:   [C]:  " −2n  + 9mn − 17np" .
_____________________________________________________

n (−6 + 27m − 51p) =

 (  n  *  −6 )  + ( n  * 27m )  −
 (  n * 51p )  ;

=  −2n  + 9mn − 17np ;  which is:  Answer choice:  [C]:  " −2n  + 9mn − 17np" .
