Sentence B is incorrect as the adjective referring to the Noun, 'Nike' should be singular, 'its' and not 'their'. Sentence C is incorrect as there is no need of a comma after concerns. Also we need to add a relative pronoun 'that' after sensing. Sentence E is incorrect as the definite article 'the' must be used in place of the indefinite article 'a'. Sentences A and D are correct.
