Step 1: Understanding the Question.
The question asks us to recall which BPO company employed the most people in India, according to a Dun and Bradstreet industry ranking from around the time of the SNAP 2007 exam.
Step 2: Key Formula or Approach.
Since this is a business current-affairs fact, the way to answer it is to recall the reported employee headcounts of the major BPO players active in India during that period.
Step 3: Detailed Explanation.
Genpact began life as GE Capital International Services, an in-house unit set up by General Electric, before it spun off into an independent company. By the mid-2000s, it had built up one of the largest workforces in the Indian ITeS and BPO industry, spanning finance, accounting, analytics, and customer support services, which is why Dun and Bradstreet ranked it as the top employer in this space.
Accenture Services had a big India presence too, but its BPO headcount in India at that time trailed behind Genpact's.
Wipro BPO was a serious player in the sector, yet its numbers also fell short of Genpact's scale.
IBM Daksh, formed after IBM acquired the Indian BPO firm Daksh eServices, was significant but again smaller than Genpact when it came to total headcount.
Step 4: Final Answer.
The company identified by Dun and Bradstreet as the largest employer among Indian ITeS and BPO firms was Genpact, so option (A) is correct.
