For the same maximum cylinder pressure and maximum temperature, the correct order of thermal efficiency among air standard cycles is:

Options:

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