a. launch submarines capable of sinking Allied ships.
b. seriously threaten to defeat the Soviet Union.
c. send waves of bombers to attack its enemies.

I would assume B. seriously threaten to defeat the Soviet Union' as the question already highlights A and C and they were allied with Japan so they wouldn't push them to surrender.
