Which one of these sentences is written incorrectly?

Question

A.
The clock's hands seemed to move in slow motion as he waited with baited breath for the teacher to call on him.
B.
"Sean," Mrs. Mosby said. Sean felt his heart stop as she continued. "You'll go first thing tomorrow morning."
C.
Sean completely forgot that everyone in his class was scheduled to gives a presentation today.
D.
"I can't leave. It's too late," Sean said as he tried to shrink himself out of the teacher's line of vision.

Answer 1

The incorrectly written sentence is:

C. Sean completely forgot that everyone in his class was scheduled to gives a presentation today.

It should be "was scheduled to give" instead of "was scheduled to gives."
