1. Chetan receives \( \frac{1}{4} \), with \( \frac{3}{4} \) remaining for Ashu and Basu. 2. Ashu and Basu contribute equally to Chetan's share. Ashu's adjusted share is \( \frac{2}{3} \times \frac{3}{4} + \frac{1}{8} = \frac{13}{24} \). Basu's adjusted share is \( \frac{1}{3} \times \frac{3}{4} + \frac{1}{8} = \frac{5}{24} \). 3. Chetan's share is \( \frac{1}{4} \), equivalent to \( \frac{6}{24} \). The resulting ratio is \( 13:5:6 \). The correct option is (A).
