Introduction:
The Solanaceae family, also known as the nightshade family, includes a variety of plants that are found all over the world. Many members of this family are known for their nutritional benefits, including being rich sources of vitamin C. In this question, we are asked to identify which member of the Solanaceae family is particularly rich in vitamin C.

Explanation:
To determine the correct option, let's analyze the vitamin C content of each of the given options:

A) Tomato:
Tomatoes, scientifically known as Solanum lycopersicum, are indeed a member of the Solanaceae family. They are widely consumed and are known for their nutritional benefits. Tomatoes are a good source of vitamin C, with an average content of about 14 milligrams per 100 grams. While this is a decent amount of vitamin C, there are other options that have higher concentrations.

B) Guava:
Guava, scientifically known as Psidium guajava, does not belong to the Solanaceae family. It is a tropical fruit that is rich in various nutrients, including vitamin C. Guava has one of the highest concentrations of vitamin C among fruits, with an average content of about 228 milligrams per 100 grams. However, since guava is not a member of the Solanaceae family, it is not the correct option.

C) Gooseberry:
Gooseberry, also known as Amla or Indian gooseberry, is scientifically known as Phyllanthus emblica. It belongs to the Euphorbiaceae family, not the Solanaceae family. Gooseberry is highly regarded for its rich vitamin C content, which is approximately 445 milligrams per 100 grams. However, since it does not belong to the Solanaceae family, it is not the correct option.

D) Strawberry:
Strawberry, scientifically known as Fragaria × ananassa, does not belong to the Solanaceae family. It is a member of the Rosaceae family. Strawberries are a good source of vitamin C, with an average content of about 60 milligrams per 100 grams. However, since strawberries are not part of the Solanaceae family, they are not the correct option.

Conclusion:
After analyzing the vitamin C content of each option, we can conclude that the correct answer is A) Tomato. While guava, gooseberry, and strawberry are also good sources of vitamin C, they do not belong to the Solanaceae family. Tomatoes, on the other hand, are a member of the Solanaceae family and contain a decent amount of vitamin C.
