Which types of plants are filled and then emptied completely after fix

1.	Which types of plants are filled and then emptied completely after fixed retention time?(a) Batch plants(b) Continuous plants(c) Floating gas holder plants(d) Flexible bag biogas plantI got this question in unit test.This question is from Anaerobic Fermentation topic in chapter Biomass Energy of Energy Engineering
Answer» Right option is (a) BATCH plants The best I can explain: Batch plants are filled and then emptied completely after a fixed retention time. Each DESIGN and each FERMENTATION material is SUITABLE for batch filling, but batch plants require high labor input.
