(B) According to the $VSEPR$ theory,a molecule with a $T$-shaped geometry arises from an $AX_3E_2$ type molecule,where $A$ is the central atom,$X$ are the bonding atoms,and $E$ are the lone pairs of electrons.In this configuration,there are $3$ bond pairs and $2$ lone pairs.The total number of electron pairs = $(	ext{Number of bond pairs} + 	ext{Number of lone pairs}) = 3 + 2 = 5$.Therefore,the total number of electron pairs in the valence shell of the central atom is $5$.
