Whilst it is not possible for snow to fall at the equator, which one of the following is most likely to cause this to happen A. ice
B. mountain
C. water
D. snow flakes​

The answer is c, i, iii, and iv. this is because farming and mining deal with harvesting raw materials, construction work falls under manufacturing, and piloting a plane is a service. ii is wrong because making bread is using  raw materials to produce goods, which would fall under the secondary sector, not primary.
