Answer : 1. "Guava "
Explanation :
(A) Guava
Guava is considered one of the richest sources of vitamin C among fruits. It contains a high concentration of ascorbic acid, which is a form of vitamin C. While other fruits like oranges and pineapples also contain vitamin C, guava surpasses them in terms of vitamin C content per serving. Tomatoes, although a good source of vitamin C, are generally lower in vitamin C compared to guava.
