The smallest composite number is 4.

\Rightarrow

The common factors of

4 = 2 \times 2 \times 1

The smallest Prime number is 2.

\Rightarrow

The common factors of

2 = 2 \times 1

Therefore,

HCF (4, 2) = 2 \times 1

\Rightarrow HCF (4, 2) = 2

Therefore, the HCF of the smallest composite number and the smallest prime number is 2.
Hence, option 2 is correct.
