Final Answer :
B
Explanation :
Phosphine (PH3) has a similar structure to ammonia (NH3), with a central phosphorus atom bonded to three hydrogen atoms and one lone pair of electrons. This arrangement leads to a trigonal pyramidal shape, not a perfect tetrahedron, because the lone pair affects the geometry, making it slightly different from a tetrahedral arrangement.
