    A) \[\operatorname{r}\,-\,\,\left( 3p\times 2q \right)=r\,-6pq\]      [binomial]

    B) \[\operatorname{r}\,-\,\,\left( 3p\times 2q \right)=r\,-8pq\]              [binomial]

    C) \[\operatorname{r}\,-\,\,\left( 3p\times 2q \right)=r\,-7pq\]           [binomial]

    D) \[\operatorname{r}\,-\,\,\left( 2p\times 2q \right)=r\,-7pq\]          [binomial]

    Correct Answer: A

    Solution :

    \[\operatorname{r}\,-\,\,\left( 3p\times 2q \right)=r\,-6pq\]      [binomial]
