16. The temperatures TC of the cold reservoirs and the temperatures TH of the hot reservoirs for four Carnot heat engines are engine 1: TC = 400 K and TH = 500 K; engine 2: TC = 500 K and TH = 600 K; engine 3: TC = 400 K and TH = 600 K; engine 4: TC = 600 K and TH = 800 K. Rank these engines according to their efficiencies, least to greatest (A) 1→2→3→4 (B) 1 and 2 tie, then 3 and 4 tie (C) 2→1→3→4 (D) 1→2→4→3 (E) 2→1→4→3
