Answer:

Introduction:
In this question, we are asked to identify the plant from which oil is not abstained. We are given four options: Mango plant, Sunflower plant, Mustard plant, and Coconut plant. We need to determine which plant does not produce oil.

Explanation:
Let's analyze each option one by one:

a) Mango plant:
Mango plants do not produce oil. The fruit of the mango plant contains a single large seed, called the mango kernel or mango stone. However, this kernel does not yield oil. Mangoes are primarily consumed as a fruit and are known for their delicious taste.

b) Sunflower plant:
Sunflower plants are one of the major sources of edible oil. The seeds of the sunflower plant are highly prized for their oil content. Sunflower oil is commonly used for cooking purposes and is known for its light flavor and high smoking point.

c) Mustard plant:
Mustard plants produce oil that is commonly known as mustard oil. The seeds of the mustard plant are crushed or pressed to extract the oil. Mustard oil is widely used in cooking, particularly in Indian and Asian cuisines. It has a strong flavor and is often used for its distinctive taste and aroma.

d) Coconut plant:
Coconut plants are another significant source of oil. The coconut itself is a fruit, and the oil is extracted from the copra, which is the dried kernel of the coconut. Coconut oil is widely used for cooking, as well as for various other purposes such as skin and hair care.

Conclusion:
After analyzing all the options, we can conclude that the plant from which oil is not abstained is the Mango plant. While sunflower, mustard, and coconut plants all produce oil, the mango plant does not yield oil.
