Correct option is A
Correct Answer: (a)
Explanation:
Amoeba typically reproduces by simple binary fission and can form cysts (encystment) under adverse conditions; it also shows regenerative ability if parts survive. Multiple fission (schizogony) is characteristic of some other protists (e.g., Plasmodium), not typical for Amoeba.
Information Booster:
Binary fission is the common asexual mode in amoebae.
Encystment helps withstand unfavorable conditions and aids transmission.
Regeneration: amoebae can reform complete cells from viable fragments.
Multiple fission involves production of many daughter cells from one parent (seen in some protozoa and algae), not standard in amoebae.
Understanding these modes helps differentiate protozoan groups in life-cycle studies.
