Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). In the light of the above statements, choose the most appropriate answer from the options given below:

The assertion holds while the reason does not, since sign systems of communication do have fixed rules and settled production procedures.

Language and other codes work through agreed grammar and conventions that let meaning be shared.

These rules are what make a sign system stable and usable within a community.

The reason fails because sign systems are not invented for cross cultural communication.

They grow within particular cultures and often differ sharply across them, which can hinder cross cultural exchange.

In this way a correct account of fixed rules stands beside a mistaken claim about their origin.
