Explanation:

Option C and D: These are mere possibilities, and not necessarily flow from disguised unemployment. In case of disguised unemployment people appear to be employed. If a work requiring at most 5 people employs 8 people, then the extra 3 do not add to the output and are essentially unemployed in disguise, i.e. underutilization of the extra labour. In India, this is more common in agriculture and low productivity sectors like small households establishments. For e.g. 90% of industrial units in India face the issue of disguised unemployment. This leads to low productivity per worker. Factors that contribute to it are: a) large unemployment: b) low skill base of labour; c) less efficient technology and capital utilization; d) sub-optimal production management etc.
