PLEASE RATE AND MARK ME AS BRAINLIST

Explanation:

1. For 4d and 5d series all ligands act as strong ligands hence pairing occur.
2. The 2 unpaired electron in 4d of Pt get paired and hence there is one vacant orbital.
3. Hence one orbital of 4d, 5s and two orbitals of 5p participates in hybridization, -> resulting in dsp2 type of hybridization and square planar geometry.
