Correct Answer: Option D
Explanation

Firstly, determine the empirical formula.

Molecular formula for the compound : C\(_6\)H\(_{12}\)O\(_6\)

To find the empirical formula, the subscripts of each element must be divided by their greatest common divisor, which is 6. 

C\(_6\)H\(_{12}\)O\(_6\)  →  CH\(_2\)O

Empirical formula : CH\(_2\)O

Now, we can calculate the empirical mass of CH\(_2\)O =  12  +  (1 x 2) + 16 

                                                                                       = 30.

:. The correct answer is option D

There is an explanation video available below.
