    Correct Answer: B

    Solution :

        A: \[\frac{2}{7}+\frac{3}{4}\,-\frac{1}{2}\,=\frac{8+21-14}{28}=\frac{15}{28}\] B: \[\frac{4}{7}+\frac{3}{2}+\frac{1}{4}\,=\frac{16+42+7}{28}=\frac{65}{28}\] C: \[\frac{6}{7}\times \left( \frac{3}{4}+\frac{9}{2} \right)=\frac{6}{7}\times \left( \frac{3+18}{4} \right)\] \[=\frac{6}{7}\times \frac{21}{4}\,=\frac{126}{28}\] D: \[\frac{5}{4}\times \,\frac{1}{7}=\frac{5}{28}\]
