entropy is the degree of disordeliness in a system.....the answer is C because the compounds given are solid and gas which react to form a solid meaning the disorderliness of the system had reduced as solids are more compacted unlike gases which are more random

yes is negative cos bond formation is exothermic reaction. but the reverse is endothermic, which is bond breaking and as such absorbs heat frm the surrounding to achieve this. And endothermic reaction is positive reason being that products formed are always bigger/ larger than reacting elements/ compounds.

I think it's supposed to be zero
in the reaction the product is a solid and solids are held by strong intermolecular forces then there is not random motion or disorderness
that is zero
