Assertion: Attitudes undergo changes and modifications through various influences, both during the process of formation and afterward.

Reasoning: Attitudes which have solidified and become deeply ingrained values for an individual cannot be changed.

Assertion (A) is true but Reasoning (R) is not correct.

Attitudes undergo changes and modifications through various influences, both during the process of formation and afterward. However, not all attitudes are equally susceptible to change. Attitudes that are still in the formative stage, resembling opinions, are more likely to be altered compared to attitudes that have solidified and become deeply ingrained values for an individual.

However, the reasoning that attitudes which have solidified and become deeply ingrained values cannot be changed is not entirely correct. While deeply ingrained attitudes may be more resistant to change compared to newly formed attitudes, they are not entirely immutable. Attitudes can still be influenced and modified, although it may require more effort and time.
