Data Sufficiency (DS) | Re: If b does not equal 0, what is the value of 4a/(3b)?

If b does not equal 0, what is the value of\frac{4a}{3b} ?
b ≠ 0,

(1)\(a = b + 2\)
\(\frac{4a}{3b} = \frac{4(b + 2)}{3b}\)
\(\frac{4a}{3b} = \frac{(4b + 8)}{3b}\)

INSUFFICIENT.

(2)\(a = 2b\)
\(\frac{4a}{3b} = \frac{4*2b}{3b}\) \(\frac{4a}{3b} = \frac{8b}{3b} = \frac{8}{3}\)
SUFFICIENT.

Answer(B).
