This is a duplicate of question 88239 about attrition rates. IT services attrition was given as 12.3%, and BPO attrition was higher at 20%. BPO operations typically experience higher attrition than IT services due to factors like repetitive work nature, younger workforce demographic, and easier substitutability of skills. Options of 6% and 10% are lower than the given IT services rate, while 100% is completely unrealistic for any business operation.
