Autophagic vacuoles fuse with - 
Select and explain. 
A. Golgi complex, B. ER, C. Lysosome, D. Mitocondria
C: Lysosome
Answer: C: Lysosome 
Explanation: Ans. is 'c' i.e., Lysosome o Autophagy is the process by which cells sequester and degrade their own cytoplasmic organelles,o During the process, autophagic vacuole is formed, which is a bilayer vacule containing unnecessary or dysfunctional organelle.o Autophagic vacule fuses with lysosome to form autophagosome (autophagolysosome).o Then, hydrolytic enzymes of lysosome degrade the organelle of autophagic vacuole.
