Pick out the part of the sentence that has an error.

A. Manju's father
B. is the one
C. who is standing
D. besides her
E. no error

Choose the correct answer from the options given below :

D only

The part of the sentence that has an error is: D only

The corrected sentence would be: "Manju's father is the one who is standing beside her."

Explanation:

The word "besides" should be corrected to "beside" to maintain proper grammar. "Beside" indicates proximity or being next to, while "besides" means in addition to. The correct phrase is "beside her" to convey that Manju's father is standing next to her.
