Answer:
B
Step-by-step explanation:
Evaluate the numerator/ denominator using order of operations
numerator = 16 + 2(4 × 2)
using the order parenthesis, multiplication followed by addition
= 16 + 2(8) ← evaluating parenthesis
= 16 + 2 × 8
= 16 + 16 ← performing multiplication
= 32 ← addition
denominator = 8 + 2³
using the order exponents then addition
= 8 + 8 ← evaluating exponent
= 16 ← addition
Hence
=
= 2 → B
