Adiploid cell the number of chromosomes as a haploid cell.
one-fourth
half
twice
four times

Twice.

Explanation:

Diploid cell may be defined as the cell that contain the diploid sets of chromosome (2X) here X represent the chromosome number. Human are diploid cell and each cell contains the set of a chromosome.  

Haploid cells contain a single set of chromosome (X). Human gametes are haploid cells. The diploid cell has twice the chromosome number as haploid cell.

Thus, the correct answer is option (3).
