Here

\(x \geq 0\)

if x = 0 , then QTY A = QTY B

if x = 2, then QTY A < QTY B

Hence option is D

Let's test some values

case i: x = 1
We get:
QUANTITY A: \(x^{10}=1^{10}=1\)
QUANTITY B: \(x^{100}=1^{100}=1\)
In this case, the two quantities are equal

case i: x = 2
We get:
QUANTITY A: \(x^{10}=2^{10}\)
QUANTITY B: \(x^{100}=2^{100}\)
In this case, Quantity B is greater

Answer: D
