Correct answer

A. 60∘,107∘60^{{}^{\circ}}, 107^{{}^{\circ}}

Step-by-step solution

In P4P_{4} molecule, the four sp 3^{3} -hybridised phosphorous atoms lie at the corners of a regular tetrahedron with ∠PPP=60∘\angle \mathrm{PPP}=60^{{}^{\circ}}. In S8\mathrm{S}_{8} molecule S-S-S angle is 107∘107^{{}^{\circ}} rings. In S8\mathrm{S}_{8} molecule S−S−S\mathrm{S}-\mathrm{S}-\mathrm{S} angle is 107∘rings.107^{{}^{\circ}} \mathrm{rings} . The P-P-P angle in P_ 4 molecule and S-S-S angle in S_ 8 molecule is(in degree) respectively
