Show answer & explanation

Answer: (C) Statement II and either I or III are sufficient

Explanation

II gives T < Q < R. With I (T < P < S), T is shorter than P, Q, R and also S (through P), so T is the shortest. With III (R < S, Q < P) as well, T < Q < P and T < Q < R < S, so again T is the shortest. II with either I or III is sufficient.
