The passage given to us explains the plight of an old woman who suffers at the hands of her wealth thirsty sons. The description given tells us that she distributes her possessions among her sons after getting impressed with the affection and devotion displayed by them despite the advices given to her by all her well-wishers. No detail given to us tells us if she started loving them more or gave gifts to them, or cooked meals or took care of them. Therefore, all the four options that refer to these aspects are wrong and only the fourth option in the provided list is correct.

We are told in the passage that her sons treated her in an unlikable manner. Therefore, the options A, D and E are completely inappropriate to be considered as the answer for this question. Option C is also not the correct answer as we find no mention of such details in the passage. The only correct answer here is option B as we find a reference to her being treated as an infectious disease in her sons’ houses.

The passage provided mentions a few excuses that are used by her sons to reject their mother, but only the last option, ‘that the education of the children suffered due to her’ stands up to the description given. The rest of the options can be valid reasons, but we find no details mentioned about them in the passage, thus they are all incorrect answers.
