The answer is: D
Explanation
The correct option is D: All of these. Here is the explanation:
Section 90 of the IPC states that a consent is not valid if it is given by a person under any of the following circumstances:
- Under fear of injury, or under a misconception of fact, and if the person doing the act knows, or has reason to believe, that the consent was given in consequence of such fear or misconception.
- By a person who, from unsoundness of mind, or intoxication, is unable to understand the nature and consequence of that to which he gives his consent.
- By a person who is under twelve years of age, unless the contrary appears from the context.
Therefore, any consent given under these conditions is not a valid consent under Section 90 of IPC.
