Doni appeared settled . . . . . . . . the crease? A. on B. at C. in D. none

The correct answer is: A. on

Doni appeared settled on the crease.

The word “crease” refers to the line in the middle of the cricket pitch. The batsman stands at the crease when batting. So, the answer “on” is the most logical choice.

The word “at” could also be used in this context, but it would be less common. The word “in” would not be a correct answer, as the batsman does not stand “in” the crease.
