Correct option is C- Assertion is correct but Reason is incorrect-SiF-4- have -sp-3- hybridization and shape of regular tetrahedral where the bond angle of -109-5-circ-which is greater than -90-circ- but less than -180-circ- -160-Repulsion sequence are -Lp -Lp -gt- Lp-Bp -gt-Bp-Bp-160-Therefore- assertion are true and reason is false-

ReasonThe lone pair-bond pair repulsion is weaker than bond pair-bond pair repulsion.AssertionAll $$F-S-F$$ angle in $$SF_4$$ greater than $$90^{\circ}$$ but less than $$180^{\circ}$$.All $$F-S-F$$ angle in $$SF_4$$ greater than $$90^{\circ}$$ but less than $$180^{\circ}$$.

Reason
The lone pair-bond pair repulsion is weaker than bond pair-bond pair repulsion.
Assertion
All $$F-S-F$$ angle in $$SF_4$$ greater than $$90^{\circ}$$ but less than $$180^{\circ}$$.
All $$F-S-F$$ angle in $$SF_4$$ greater than $$90^{\circ}$$ but less than $$180^{\circ}$$.
