For the SAME compression ratio $r$ and heat input, the thermal efficiencies of the air-standard cycles compare as:

Options:

• (A) $\eta_{Otto} > \eta_{Dual} > \eta_{Diesel}$
• (B) $\eta_{Diesel} > \eta_{Dual} > \eta_{Otto}$
• (C) $\eta_{Otto} = \eta_{Diesel}$
• (D) $\eta_{Dual} > \eta_{Otto} > \eta_{Diesel}$
