Acc to options sporulation is correct answer over here.As far as unfavourable condition is said then obviously encystation occurs and is the accurate answer to this question.

Unfavorable condition me amoeba apne around ek hard covering bna leta b jiso hm encystation kehte h or favourable condition aane pe wo continuous divide krta h or bhut saare minute amoeba bna leta h jinko hm pseudospores bolte h or is phenomenon ko hm sporulation bolte h

Actually amoeba forms a cyst around itself in unfavourable condition. At that time amoeba divides by multiple fission . Later when the favourable condition returns the walls bursts out then the spores which are formed after multiple fission spreads out in the atmosphere. So technically it reproduces ( or divides as in unicellular organisms like amoeba this are similar ) by MULTIPLE FISSION. I can clearly confirm it is multiple fission you can check any websites. I don't know why so much answer is speaking it as sporulation it is the process by which they spread in atmosphere. Reproduction is by multiple fission.

A method known as multiple fission in adopted by the unicellular organisms amoeba to survive and reproduce under unfavorable conditions, when the condition are unfavorable amoeba withdraws it's psuedopodies and becomes almost round.

In unfavourable conditions certain organism produce spore.This is a method of asexual reproduction which we already study in previous classes.

I verified your answer by many experts. None of the above is correct answer.In ream sense the amoeba (under unfavorable conditions) reproduce by Multiple fission. Under Multiple fission is does undergoes ENCYTATION. In Encytation amoeba withdraws its pseodopodia and forms a three layerd wall known as cyst wall.

During unfavorable conditions amoeba divides by sporulation but as it forms man daughter cells so it must considered as multiple fission.

A . multiple fission
during unfavourable condition , cell membrane disapper and cytoplasm spread around nucleus and form cyst. then a multiple daughter cell release by multiple fission .

During unfavourable conditions like abundance of food ,the amoeba undergoes multiple fission where equational division forms amoebulae under encystment stage .The thick wall is later on bursted thereby giving rise to daughter amoeba.

Bcoz they don't get sufficient food to survive and unfavorable conditions like surrounding climate. Hence the reproduction occurs in multiple fission
