43.
The answer is: A
Explanation
The correct option is A: 2002.
The reason is that Section 89 of the Code of Civil Procedure, which provides for settlement of disputes outside the court through methods such as mediation, conciliation and arbitration, was added by the Code of Civil Procedure (Amendment) Act, 1999. This amendment act came into force on July 1, 2002. Therefore, Section 89 has been included in the code since 2002.
The other options are incorrect because they are not the year when Section 89 was introduced in the code. Section 89 was not part of the original Code of Civil Procedure, 1908, nor was it added by any subsequent amendment acts in 2004, 2012 or 2013.
