The sentence contrasts the different responses to football and cricket. "Lukewarm" implies a weak or indifferent response, which is appropriate for the relatively lower popularity of football in India compared to cricket. "Electrifies" in the second part of the sentence implies a strong and exciting reaction, which fits the intense passion cricket generates in India.
Option (A), tepid ... boiling, is incorrect because "tepid" suggests lukewarm or indifferent, but "boiling" does not match the tone of the second part of the sentence, which is about cricket’s electrifying influence.
Option (C), turbid ... fascinating, doesn't fit as "turbid" refers to something cloudy or unclear, which doesn’t fit the context of a response. "Fascinating" doesn't match the intensity implied by "electrifies."
Option (D), apocryphal ... genuinely fascinates, is incorrect because "apocryphal" refers to something of doubtful authenticity, which doesn't apply to the context of comparing football and cricket responses in India. "Genuinely fascinates" also doesn't convey the intensity needed in this sentence.
Thus, option (B) is the most appropriate choice.
