The given numbers are 16.5,0.90 and 15

Multiplying each number by 100 we get 1650,90 and 1500

Let us consider the numbers 1650,90 and 1500

By prime factorization, we get,

1650 = 2 × 3 × 5²× 11

90 = 2 × 3²× 5

1500 = 2²× 3 × 5³

H.C.F. of 1650.90 and 1500 is 2 × 3 × 5 = 30

Therefore, H.C.F. of 16.5,0.90 and 15 will be

\frac{30}{100}

= 0.30

So, option D is correct.
