Concept:The question asks to arrange four sentence parts (P, Q, R, S) in a logical order to form a coherent paragraph between sentence 1 and sentence 6.
Explanation:Sentence 1 states that exercise keeps the body fit and active.
Sentence S gives a specific benefit: physical activity strengthens the heart and muscles. So S comes first.
Sentence P adds another benefit: it boosts mental health. So P follows S.
Sentence R provides examples of easy exercises like walking and cycling. This comes next.
Sentence Q tells how regular workouts reduce stress. This logically concludes the benefits before sentence 6.
Thus the correct order is S, then P, then R, then Q.
Answer:SPRQ (Option A)
