Select the best option for the sentence given below in order to make it grammatically correct

Reynolds told his aunt he would not mind standing and eat dinner as he is in a hurry to reach the bus station.

The correct answer is Option A. 

Reynolds told his aunt he would not mind standing and eating dinner as he was in a hurry to reach the bus station.

The phrase “standing and eat dinner” needs improvement. When using “mind,” we follow it with a gerund (the base form of the verb + “ing”).
So, we need to change “eat” to “eating.” To maintain a parallel structure, both gerunds should be in the same form. Therefore, we say “standing and eating.”

Although D looks similar to A, the issue with option D lies in the word “hurry.” 

In English, we use the phrase “in a hurry” to express that someone is rushing or has limited time. The correct form should be “in a hurry,” not just “in hurry.”
