The gravitational effect of which of the following causes tides in the sea?

Options

A. Jupiter
B. Sun
C. Moon
D. Both (a) and ( c )

Answer

To solve the question regarding which celestial bodies cause tides in the sea, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Tides**: Tides are the rise and fall of sea levels caused by the gravitational forces exerted by celestial bodies. The most significant of these bodies are the Moon and the Sun.

2. **Identifying Gravitational Effects**: The gravitational pull of these celestial bodies affects the water in the oceans. The Moon, being the closest celestial body to Earth, has a strong gravitational effect on the oceans, leading to the formation of tides.

3. **Considering Other Celestial Bodies**: While the Moon is the primary cause of tides, other large celestial bodies, such as Jupiter, also exert a gravitational force on Earth. Although Jupiter is much farther away than the Moon, its massive size means it can still influence tides to a lesser extent.

4. **Evaluating the Options**: In the given options, we need to identify which celestial bodies are mentioned. The options include:
- A) Jupiter
- B) Mars
- C) Moon
- D) Both A and C

5. **Conclusion**: Since both the Moon and Jupiter can cause tides, the correct answer is option D) Both A and C.

### Final Answer:
The gravitational effect of the Moon and Jupiter causes tides in the sea. Therefore, the correct answer is option D) Both A and C.
