Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Read the statements and choose the correct answer using the code given below.

Assertion (A): Obesity is caused by excessive intake of fat that accumulates in the body.

Reason (R): The excessive fat is not metabolised due to lack of physical activity.

Explanation:

The assertion (A) states that obesity is caused by excessive intake of fat that accumulates in the body.

• This is generally true because consuming more calories than the body needs can lead to weight gain and obesity.
• Fat is a concentrated source of calories, and when consumed in excess, it can contribute to weight gain.

The reason (R) supports the assertion by explaining that the excessive fat is not metabolized due to a lack of physical activity.

• Physical activity plays a crucial role in the body's metabolism, including the breakdown and utilization of fat stores.
• When physical activity is insufficient, the body may not effectively metabolize the excess fat consumed, leading to its accumulation and the development of obesity.

Therefore, both statements are true, and the reason provides a logical explanation for the assertion, making the statement "Both (A) and (R) are true, and (R) is the correct explanation of (A)" the correct answer.
