Reason R: Turpentine oil is costlier than other thinners.

Which of the following is correct?

1. A is false but R is true
2. A is true but R is false
3. Both A and R are true, but R is not a correct explanation of A
4. Both A and R are true, and R is the correct explanation of A.

Answer 1

Correct Answer - Option 3 : Both A and R are true, but R is not a correct explanation of A

Explanation: 

Turpentine oil  - Turpentine is a fluid obtained by the distillation of resin harvested from living trees, mainly pines. Mainly used as a specialized solvent, it is also a source of material for organic syntheses. It is recommended as thinner for indoor painting because Turpentine accelerates the drying time faster than most paint thinners or mineral spirits among other things because it accelerates the polymerization of the oil film since it incorporates oxygen into the mix oxidizing the paint layer from the inside out. And Turpentine oil is costlier than other thinners. 

Therefore, Both are correct but R is not the correct explanation of A.
