• C. Wooden ball will float.
• D. Wooden ball will sink.

Answer 1

Answer: (B), (C)

The correct options are
B Iron ball will sink.
C Wooden ball will float.

An iron ball is more dense than water whereas wooden ball is less dense than water. Therefore, for the same volume of water, weight of iron ball is more than that of water and weight of wooden ball is less than that of water. Hence, iron ball will sink and wooden ball will float.
