Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

'During' is correct because it indicates the time period when something happened. 'During his illness' means 'in the time period of his illness'. 'Since' implies cause, 'Along' suggests accompaniment, and 'Before' indicates prior timing - none fit the context of gradual weakening over the illness period.
