If X is a discrete random variable that follows Binomial distribution, then which one of the following response relations is correct?

A) $${\text{P}}\left( {{\text{r}} + 1} \right) = \frac{{{\text{n}} - {\text{r}}}}{{{\text{r}} + 1}}{\text{P}}\left( {\text{r}} \right)$$ B) $${\text{P}}\left( {{\text{r}} + 1} \right) = \frac{{\text{p}}}{{\text{q}}}{\text{P}}\left( {\text{r}} \right)$$ C) $${\text{P}}\left( {{\text{r}} + 1} \right) = \frac{{{\text{n}} + {\text{r}}}}{{{\text{r}} + 1}}\frac{{\text{p}}}{{\text{q}}}{\text{P}}\left( {\text{r}} \right)$$ D) $${\text{P}}\left( {{\text{r}} + 1} \right) = \frac{{{\text{n}} - {\text{r}}}}{{{\text{r}} + 1}}\frac{{\text{p}}}{{\text{q}}}{\text{P}}\left( {\text{r}} \right)$$
