Answer: The correct option is (a) x .

Step-by-step explanation: We are given to choose the solution set for the following inequality :


x+2<-5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

The solution of inequality (i) is as follows :


x+2<-5\\\\\Rightarrow x<-5-2\\\\\Rightarrow x<-7.

Therefore, the solution set for the given inequality is all real numbers less than -7.

That is, the solution set is x ∈ R, x < -7.

Thus, the required solution set is x .

Option (a) is CORRECT.
