Answer:

B

Explanation:

To find
y=f(g(x)) , substitute the value of
g(x) into the the function f(x) instead of x.

Consider option B:

Given

$f(x)=(7)/(√(x))\\ \\g(x)=8x+10$

So,

$f(g(x))\\ \\=f(8x+10)\ [\text{Expression } 8x+10\text{ has a role of }x]\\ \\=(7)/(√(8x+10))$

This is exactly what you need as answer.
