    Answer : Option B

    Explanation :

    Make the same number of decimal places. The given numbers are 3.00, 2.70, and 0.09.
    Without decimal places, these numbers are 3, 27, and 9.
    Now, the HCF of 3, 27, and 9 is 3.
    So, the HCF of 3, 2.7, and 0.09 is 0.03
    Now, the LCM of 3, 27, and 9 is 27.
    So, the LCM of 3, 2.7, and 0.09 is 0.27
