A relation $R$ is defined from $\{2,\mathrm{ }3,\mathrm{ }4,\mathrm{ }5\}$ to $\{3,\mathrm{ }6,\mathrm{ }7,\mathrm{ }10\}\mathrm{ }$ by $\mathrm{x} R \mathrm{y}\Rightarrow \mathrm{x}$ is relatively prime to $\mathrm{y}$, then domain of $R$ is

• A

  $\{2,\mathrm{ }3,\mathrm{ }5\}$
• B

  $\left\{3,\mathrm{ }5\right\}$
• C

  $\left\{2,\mathrm{ }3,\mathrm{ }4\right\}$
• Correct answer
  D

  $\left\{2,\mathrm{ }3,\mathrm{ }4,\mathrm{ }5\right\}$

Hence, the correct answer is option: 'D'.
