**Core Concept**
The concept of valid consent in medical law is crucial, and age is a significant factor in determining capacity for informed consent. The Indian Penal Code (IPC) defines the age of majority and the capacity to give consent.

**Why the Correct Answer is Right**
The correct IPC code related to age for valid consent is Section 88, which states that a person is deemed to have attained the age of majority at 18 years. This means that an individual below the age of 18 is considered a minor and lacks the capacity to give informed consent. According to the Indian Contract Act, 1872, a minor's consent is not valid for any agreement or contract. This is because minors are considered incapable of understanding the nature and consequences of their actions, and their decisions may be influenced by others.
