In the statement, tick 'T' against those which are true, and 'F' against those which are false.
Sound cannot travel in vacuum.

Options

A. True
B. False
C. May be
D. Depends on situation

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement given is "Sound cannot travel in vacuum." We need to determine if this statement is true or false.

2. **Definition of Sound**: Sound is a type of mechanical wave. This means that it requires a medium (like air, water, or solids) to travel through.

3. **Medium Requirement**: For sound to propagate, it needs particles to vibrate and transmit the sound waves. In a vacuum, there are no particles present.

4. **Conclusion**: Since sound requires a medium to travel and cannot propagate in a vacuum (where there are no particles), the statement "Sound cannot travel in vacuum" is indeed true.

5. **Marking the Statement**: Based on the evaluation, we will mark 'T' (True) against the statement.

**Final Answer**: T (True)
