Correct answer is option C because Carrot is a root  but other three are vegetables that grow on plants.

Explanation:

Introduction:
In this question, we are given a set of four options: Tomato, Carrot, Brinjal, and Gourd. We need to identify the odd one out from these options.

Analysis of options:
Let's analyze each option one by one:

a) Tomato: Tomato is a fruit that is commonly used as a vegetable in cooking. It belongs to the nightshade family. It is typically red in color and has a juicy and pulpy texture.

b) Carrot: Carrot is a root vegetable that is widely consumed. It is known for its bright orange color and crunchy texture. Carrots are rich in vitamins, minerals, and dietary fiber.

c) Brinjal (Eggplant): Brinjal is a vegetable that is widely used in various cuisines. It belongs to the nightshade family and comes in different colors, including purple, green, and white. Brinjal has a slightly bitter taste and a spongy texture.

d) Gourd: Gourd is a collective term for various vegetables that belong to the Cucurbitaceae family. Examples of gourds include bottle gourd, bitter gourd, and ridge gourd. Gourds have a hard outer shell and a soft flesh inside.

Identifying the odd one out:
From the given options, the odd one out is Carrot (option b). The reason is that all the other options (Tomato, Brinjal, and Gourd) belong to the nightshade family, while Carrot belongs to the Apiaceae family. Additionally, Carrot is a root vegetable, whereas the other options are fruits or vegetables with seeds.

Conclusion:
In conclusion, the odd one out from the given options is Carrot (option b) because it does not belong to the nightshade family and is a root vegetable, unlike the other options.
