Answer: The correct option is (c). $\csc x=\dfrac{1}{\sin x}.$

Step-by-step explanation: We are given to select the correct basic identity that we will use to verify the following:

$\dfrac{\sin x+1}{\sin x}=1+\csc x.$

We have

$\dfrac{1+\sin x}{\sin x}\\\\\\=\dfrac{1}{\sin x}+\dfrac{\sin x}{\sin x}\\\\\\=1+\dfrac{1}{\sin x}.$

In order to verify the given trigonometric equation, we must have

$1+\dfrac{1}{\sin x}=1+\csc x\\\\\\\Rightarrow \dfrac{1}{\sin x}=\csc x\\\\\\\Rightarrow \csc x=\dfrac{1}{\sin x}.$

Thus, the required identity that we will use is

$\csc x=\dfrac{1}{\sin x}.$

Option (c) is CORRECT.
