Thin film deposition is a process where: a) - elemental, alloy, or compound thin films are deposited onto a bulk substrate! b) - Phosphatization is also applied c) - Zinc plating is also applied d) - None of the above

(A) elemental, alloy, or compound thin films are deposited on to a bulk substrate

Explanation:

In film deposition there is process of depositing of material in form of thin films whose size varies between the nano meters to micrometers onto a surface. The material can be a single element a alloy or a compound.

This technology is very useful in semiconductor industries, in solar panels in CD drives etc

so from above discussion it is clear that option (a) will be the correct answer
