Solution:• This question contains a factual error in its premise. India won the 2011 Cricket World Cup, defeating Sri Lanka in the final. No team defeated India in the men's category to eliminate them from the tournament. India won all their knockout matches.Let's re-evaluate based on the options, assuming the question might be flawed or refers to an earlier stage match where India lost, but still progressed.
• In the group stage of the 2011 Cricket World Cup, India's only loss was against South Africa. However, the question asks "Which country defeated India... in the 2011 Cricket World Cup" which implies their elimination, which didn't happen as they won.
