Read the following statements and choose the correct option :
Assertion (A) : A plan for individualised learning must be created by a language teacher.
Reason (R) : There is diversity in learners in the learning of new languages.

The correct option is Both (A) and (R) are true, but (R) is not the correct explanation of (A).

Analysis of Assertion (A):
Assertion (A) states: "A plan for individualised learning must be created by a language teacher."
This statement is true. Individualised learning plans (ILPs) allow teachers to cater to unique learning speeds, styles, and needs of individual students, helping optimize language acquisition for each learner.

Analysis of Reason (R):
Reason (R) states: "There is diversity in learners in the learning of new languages."
This statement is also true. Learners differ in background, aptitude, native language influence, motivation, and cognitive preferences when acquiring a new language.

Relationship between Assertion (A) and Reason (R):
While both statements are factually correct, learner diversity is a broad concept that justifies differentiated instruction in general, but does not strictly dictate that an individualised plan *must* be created for every single learner in all contexts (as whole-class and collaborative learning strategies are also widely used and effective). Therefore, Reason (R) is not the direct or complete explanation for Assertion (A).
