If we look at options now, Option A is All these plants belong to Solanaceae. This option is the correct one as Brinjal, Tobacco, Potato and Tomato belong to the family Solanaceae and the similarity between them is asked in the question due to which this option becomes the correct one.
Moving to option B i.e., All these plants belong to Malvaceae. This option is incorrect as in the question similarity between Brinjal, Tobacco, Potato and Tomato is asked and all these plants do not belong to the Malvaceae family but they belong to Solanaceae family. Therefore, this option is incorrect and hence gets eliminated.
Moving to option C i.e., All are vegetables. This option is also incorrect as in the question similarity between the given plants is asked but all these are not vegetables due to which this option is incorrect and hence it gets eliminated.
Last option D is Fruits of all has economic importance. This option is also incorrect as fruits of all the given plants do not have economic importance and, in the question, similarity has been asked due to which this option becomes incorrect and hence gets eliminated.
Thus, the right option is A.
