    Solution:

    We have to find the product of HCF and LCM of smallest prime number and smallest composite number.
    Smallest prime number is 2.
    Smallest composite number is 4.
    LCM of 2 and 4 is the least common multiple.
    Therefore, LCM is 4.
    HCF is the highest common factor. Therefore, the highest common factor between 2 and 4 is 2.
    Product of HCF and LCM of smallest prime number and smallest composite number is,
    P=2×4   ⇒ P = 8
    Therefore, the product of HCF and LCM of smallest prime number and smallest composite number is 8.
    Hence, option (1) is correct.
