Explanation:

Let’s break it down:

- The term “foreign judgment” is specifically defined in the Code of Civil Procedure, 1908.

- Here’s what really matters: Section 2 of the CPC is about definitions in general, but it does not define "foreign judgment."

- Section 3 talks about other things: hierarchy of courts, not relevant here.

- Section 6 is about pecuniary jurisdiction—again, not about foreign judgments.

- Section 13 is the actual place where you get the definition and the rules about foreign judgments. It describes when a foreign judgment is conclusive in Indian law.

So, the correct option is:

Option:4, 13
