Explanation:

To determine the age of consenting party under Section 88, it's essential to understand the context or jurisdiction as laws vary across regions. Therefore, consider these general points:

- Option 1: At least 12 years.

- Some jurisdictions may allow minors to consent to certain non-criminal acts, but 12 is typically too young for significant legal consent, especially in a global context for major decisions like marriage or medical procedures.

- Option 2: At least 18 years.

- Generally accepted in many places as the age of majority. It's when individuals are legally recognized as adults and can make binding decisions for themselves.

- Option 3: At least 10 years.

- Usually considered a minor age, not appropriate for consenting in serious contexts.

- Option 4: At least 7 years.

- Similar to Option 3, too young for any legally binding decisions.
