Solution

The correct option is B $14 = 2 \times 7$
Prime factorization involves only prime numbers.

$(i) 20 = 2 \times 10$
Here, 10 is not a prime number.

$(i i) 14 = 2 \times 7$
is a prime factorization.

$(i i i) 64 = 4^{3}$
Here, 4 is not a prime number.

$(i v) 120 = 2^{3} \times 15$
Here, 15 is not a prime number.
