Composition of function is substitution. You substitute one function into another one. For instance,
[tex]\sf f(x)=x^2}[/tex]
[tex]\sf g(x)=7x[/tex]
[tex]\sf f(g(x))=?}[/tex]
We substitute the function "g" instead of x.
[tex]\sf f(g(x))=(7x)^2}[/tex]
And now simplify.
[tex]\sf f(g(x))=49x^2}[/tex]
[tex]\sf \therefore, option [b] is\,correct! (:[/tex]
