Mr. Rajendran is still . . . . . . . . leave. A. on B. in C. to D. by

The correct answer is: C. to

The word “to” is used to indicate a destination or purpose. In this case, Mr. Rajendran is still preparing to leave.

The other options are incorrect because they do not make sense in the context of the sentence.

• “On” is used to indicate a surface or location. For example, “Mr. Rajendran is on the bus.”
• “In” is used to indicate a location or position inside something. For example, “Mr. Rajendran is in the car.”
• “By” is used to indicate a means of transportation or communication. For example, “Mr. Rajendran is going to the airport by car.”
