ગણ $\left\{\frac{1}{2}, \frac{2}{3}, \frac{3}{4}, \frac{4}{5}, \frac{5}{6}, \frac{6}{7}\right\}$ ને ગુણધર્મની રીતે દર્શાવો. 

• A
  $\{ x : x = \frac{n}{n+1}, n \in \mathbb{N}, 1 \le n \le 6 \}$
• B
  $\{ x : x = \frac{n}{n+1}, n \in \mathbb{N}, 1 \le n < 6 \}$
• C
  $\{ x : x = \frac{n}{n+1}, n \in \mathbb{N}, 1 < n \le 6 \}$
• D
  $\{ x : x = \frac{n}{n-1}, n \in \mathbb{N}, 1 \le n \le 6 \}$
