The correct option is B Agricultural workers
Disguised unemployment is mostly found among agricultural workers who work for small farmlands. There are more people in agriculture than necessary. So, even if a few people are moved out, production will not be affected. In other words, workers in the agricultural sector are underemployed. This kind of underemployment remains hidden in contrast to the situation of someone who does not have a job and is clearly unemployed. Hence, it is also known as disguised unemployment.
