Step-by-step explanation:
Answer:
Option 1 is correct.
Step-by-step explanation:
Given two functions f(x)=sec x and g(x)=arcsin x
we have to find f(g(x)).
f(g(x))=sec(arcsinx)=sec A where A=arc(sinx)
As, A=arc(sinx)
⇒ 
⇒ P=x and H=1 gives 
hence, 
hence, 
Rationalizing, we get

Option 1 is correct.
