**Core Concept**
The concept of rape is a serious violation of personal autonomy and consent, particularly when it involves individuals who are minors or have diminished capacity to provide informed consent. In this context, the age of the woman is a critical factor in determining the legitimacy of consent.

**Why the Correct Answer is Right**
In many jurisdictions, including India, a woman is considered a minor until the age of 18 years. According to the Indian Penal Code (IPC), the age of consent is 18 years, and any sexual activity with a minor is considered statutory rape, regardless of whether consent was given or not. This is because minors are not considered capable of providing informed consent due to their age, immaturity, and vulnerability.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the age of consent can vary across jurisdictions, and the specific age may not be universally applicable.
**Option B:** This option is incorrect because it does not specify the age of consent, making it an ambiguous and potentially incorrect choice.
**Option C:** This option is incorrect because it does not accurately reflect the age of consent in most jurisdictions, including India.

**Clinical Pearl / High-Yield Fact**
It is essential to remember that the age of consent is a critical factor in determining the legitimacy of consent, and any sexual activity with a minor is considered a serious crime, regardless of whether consent was given or not.

**Correct Answer: C. 18 years.**
