Answer:

The correct option is B)
n\geq (-3c+9)/(p).

Explanation:

Consider the provided inequality:


-np - 6 \leq 3(c - 5)

Now distribute 3 inside the parentheses.


-np - 6\leq 3c - 15

Add 6 on both the side of the inequality:


-np-6+6\leq 3c-15+6


-np\leq 3c-9

Now, multiply both the sides by a negative sign and reverse the sign of inequality.


np\geq -3c+9

Divide both the sides of the inequality by p.


n\geq (-3c+9)/(p)

Now consider the provided options.

By observing the provided option it can be concluded that the correct option is B)
n\geq (-3c+9)/(p).
