P and As form d π-d π bond with transition elements when their compounds like P ( C 2 H 5)3 and As ( C 6 H 5)3 act as ligands.

I and II

II and III

I and III

All of these

P and As form dπ−dπ bond with transition elements when their compounds like P(C2​H5​)3​ and As(C6​H5​)3​ act as ligands.

$P$ and As form $d π - d π$ bond with transition elements when their compounds like $P (C_{2} H_{5})_{3}$ and $A s (C_{6} H_{5})_{3}$ act as ligands.
