The answer is B. [tex] \frac{1}{3} [/tex].
Use PEMDAS to solve the exponents first, multiply/divide, etc.
[tex] \frac{5-8/2+6}{4+4*2+3^2} [/tex]
[tex] \frac{5-8/2+6}{4+4*2+9} [/tex]
[tex] \frac{5-4+6}{4+8*9} [/tex]
[tex] \frac{1+6}{4+17} [/tex]
[tex] \frac{7}{21} [/tex]
Divide both 7 and 21 by 7 to simplify to [tex] \frac{1}{3} [/tex].
