Right choice is (b) Small-size bioreactors are used

Explanation: Usually in submerged liquid fermentation, the bioreactor used are of larger size because the concentration of media is less and is diluted. The small-sized bioreactors can be used in the solid-state fermentation. However, the sampling is easy for biomass measurement but the downstream processing is difficult and very expensive.
