Answer 1

Answer:

Option D is correct

Step-by-step explanation:

We know that the rational number having denominator 3,7,9,11,13,17,23,27... and multiple of these number, will have a non-terminating decimal expansion.

Here the decimal expansion is 327.7081, which is terminating.

Then, the prime factors of q, when this number is expressed in the form qp will be 2 or 5 or both.
