Assertion (A) : Amoeba reproduces by fission.

Reason (R) : All unicellular organism reproduce by asexual methods.

(A) and (R) both correct, and (R) is correct explanation of (A)

(A) and (R) both correct, but (R) is not the correct explanation of (A)

(A) is correct, (R) is wrong

(A) is wrong, (R) is correct

A is correct and R is wrong

An Amoeba is a type of cell or organism which has the ability to alter its shape, primarily by extending and retracting pseudo-pods.In Amoeba, binary fission is a type of asexual reproduction practiced by unicellular organisms in which the parent cell divides into two daughter cells.
No—at least not exclusively asexually. Many alternate between sexual and asexual phases of the life cycle. Among protozoans, amebae and flagellates have only asexual reproduction, but there are many others such as Paramecium and the malaria parasites (Plasmodium), as well as some unicellular algae like Chlamydomonas, that have sexual stages in their life cycles. In Paramecium, it involves an exchange of DNA called conjugation.

Hence option 3rd is correct.
