Answer:
C). Makes the reader want to find out what happens next.
Step-by-step explanation:
The given excerpt from 'Heart of a Samurai'(assumed) develops suspense by presenting the events in a manner that leaves the readers puzzled and uncertain about 'what would happen next.' The situation of impending danger on Manjiro when 'two boats move towards the island and his heart beat deep in his stomach and weak limbs feeling numb' develops a feeling of tension as well as empathy among the readers towards the character. The further details like 'he might faint...croaked..boats!..rescue!' takes the excitement and anxiousness at the peak. Therefore, option C is the correct answer.
