Identify the correct pair of species with the correct description

A

$$\text{CH}_4 \rightarrow {}^-\text{CH}_3$$ with change in both hybridization and shape

B

$$\text{NH}_3 \rightarrow \text{NH}_4^+$$ with no change in shape and change in hybridization

C

$$\text{BF}_3 \rightarrow \text{BF}_4^-$$ with change in both hybridization and shape

D

$$\text{H}_2\text{O} \rightarrow \text{H}_3\text{O}^+$$ with no change in hybridization as well as shape
