Explanation:

This is an easy question the fifth paragraph states that “Disruptive products nearly always promise lower profit margins…they are not attractive to the company’s best customers”. Also, the first sentence of paragraph 3 states that “Disruptive innovations create an entirely new market”. It is clear that the new market will always be smaller than established markets. From this, [2] can be inferred. [1] is incorrect as it states that the changes due to DI are not useful which is contrary to the passage. The passage does not state that investment in DI requires large investment/resources or can only be done by large companies. On the contrary, the reverse (small investments and smaller companies implement DI) is true as per the passage. Eliminate [3] and [4].
Hence, the correct answer is option 2.
