Answer:

B. Decrease [tex]a[/tex].

Step-by-step explanation:

The grade of vertical compression of the function [tex]y = a\cdot \sin (b\cdot x)[/tex] is related with its amplitude, represented by variable [tex]a[/tex]. If we know that [tex]a > 0[/tex], then compression is related to a decrease on [tex]a[/tex]. Therefore, the correct answer is B.
