Answer:

Option C $3n^{2}+n-2$

Step-by-step explanation:

Verify each expression

case A) we have

$5n^{2}+6n-1$

In this expression the term of n is 6n

has a coefficient of positive 6

case B) we have

$2n^{2}-5n+1$

In this expression the term of n is -5n

has a coefficient of negative 5

case C) we have

$3n^{2}+n-2$

In this expression the term of n is n

has a coefficient of positive 1

case D) we have

$4n^{2}-n+9$

In this expression the term of n is -n

has a coefficient of negative 1
