A relation `R` is defined from `{2,3,4,5,}` to{3, 6, 7, 10}by `: x R y :x` is relatively prime to `ydot` Then, domain of `R` is (a)`{2,3,5,}` (b) `{3,5,}` (c) `{2,3,4,}` (d) `{2,3,4,5,}dot`

Explanation

To solve the problem, we need to determine the domain of the relation \( R \) defined from the set \( \{2, 3, 4, 5\} \) to the set \( \{3, 6, 7, 10\} \) where \( x R y \) means \( x \) is relatively prime to \( y \).

### Step-by-Step Solution:

1. **Understanding Relatively Prime**:
Two numbers \( x \) and \( y \) are relatively prime if their greatest common divisor (gcd) is 1. This means they do not share any prime factors.

2. **Evaluate Each Element in the Domain**:
