Correct option is B
The correct answer is
(b) shall wear in the evening.
Explanation:
The use of "shall" is incorrect here when referring to a general statement or action. In modern usage, "shall" is rarely used except in very formal situations. The correct verb phrase should be "can wear" or "will wear." Hence, the correct part is the verb phrase, which causes the error.
Corrected sentence:
"I am sure my mother has something that you
can wear in the evening."
