Which of the following factors made the services offered by the Indian IT attractive to the US? A. Indian IT companies had expertise in rare core operations B. The US lacked the necessary infrastructure and personnel to handle mass call centre operations C. Inability of other equally cost-efficient developing countries to comply with their strict policies

The passage states that American executives were quick to capitalize on 'cost savings to be gained by outsourcing noncore operations'—not core or rare operations (A is wrong). The passage does not mention US lacking infrastructure (B is wrong). It does not mention other countries' inability to comply with strict policies (C is wrong). Hence none of the listed factors made Indian IT services attractive per the passage—option (1) is correct.
