JEE Main 2013 Physics question

Wax is coated on the inner wall of a capillary tube and the tube is then dipped in water. Then, compared to the unwaxed capillary, the angle of contact θ and the height h upto which water rises change. These changes are :

• (1)θ increases and h also increases
• (2)θ decreases and h also decreases
• (3)θ increases and h decreasesCorrect
• (4)θ decreases and h increases
