Concept:Fruits are classified by the number of flowers and carpels involved in their formation.
Explanation:A simple fruit forms from one flower with a single ovary or fused carpels, such as mango and orange.
A multiple fruit develops from many flowers that fuse together, such as pineapple.
An aggregate fruit develops from one flower that contains many separate carpels.
Each carpel ripens into a small fruiting unit, and these units cluster together on the same receptacle.
Examples of aggregate fruits include raspberry, blackberry, and strawberry.
A false fruit, also called an accessory fruit, develops from floral parts other than the ovary, such as pear and cashew.
Therefore, the fruit produced by one flower with many carpels is an aggregate fruit.
Answer:The correct option is C. aggregate.
