B. 403/9900000
C. 403/100000000
D.403/1000000000
E. None

Option A: is the correct answer.

Option C: is the correct answer.

Explanation:

Option A:

Dividing, we get,

Hence, dividing the fraction we get the rational number

Thus, Option A is the correct answer.

Option B:

Dividing, we get,

Hence, dividing the fraction we get the rational number which is not equivalent to the rational number

Thus, Option B is not the correct answer.

Option C:

Dividing, we get,

Hence, dividing the fraction we get the rational number which is equivalent to the rational number

Thus, Option C is the correct answer.

Option D:

Dividing, we get,

Hence, dividing the fraction we get the rational number which is not equivalent to the rational number

Thus, Option D is not the correct answer.

Option E: None

Among all the above options, Option A and C is the correct answer.

Thus, we cannot say there is no correct option.

Hence, Option E is not the correct answer.
