What is the best time 2 eat fruit?is it true that eating fruit right after a meal causes acidity?

Anytime. no: You can eat it whenever you want.

No single answer but: Some nutritionists feel morning is the best time to eat fruit & that it is best digested on an empty stomach or with dairy, nuts & seeds or greens. These theories are based on the process of how we digest. Many say melons esp. Are best on an empty stomach. See http://www.Centerholistic.Com/index.Php/health/food-combining and see my comments. Whether its ok after a meal is controversial.
