Oceans are present on Earth surface is

Options

A. `3//4`
B. `1//2`
C. `1//4`
D. `2//3`

Explanation

To determine the fraction of the Earth's surface that is covered by oceans, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the fraction of the Earth's surface that is covered by oceans.

2. **Recall the Facts**: It is known that approximately 71% of the Earth's surface is covered by water, which includes oceans, seas, and other bodies of water.

3. **Convert Percentage to Fraction**: To express 71% as a fraction, we can convert it:
\[ 71\% = \frac{71}{100} \]
However, for simplicity and common knowledge, we can approximate this to the fraction \(\frac{3}{4}\) (since \(\frac{3}{4} = 0.75\) or 75%, which is close to 71%).

4. **Analyze the Options**: The options given are:
- A) \(\frac{3}{4}\)
- B) \(\frac{1}{2}\)
- C) \(\frac{1}{4}\)
- D) \(\frac{2}{3}\)

5. **Select the Correct Answer**: Since we have established that approximately \(\frac{3}{4}\) of the Earth's surface is covered by oceans, we can conclude that the correct answer is:
\[ \text{Option A: } \frac{3}{4} \]

### Final Answer:
The correct answer is **Option A: \(\frac{3}{4}\)**.
