Step 1: Understanding the modes of asexual reproduction.
Asexual reproduction occurs without the involvement of gametes and includes several types such as binary fission, budding, conidia, and fragmentation. Let's match these with the organisms that use these methods.
Step 2: Analyzing the options.
(A) Binary fission: Correct match is with iii Spirogyra, which reproduces by binary fission.
(B) Conidia: Correct match is with iv Penicillium, which produces conidia as a form of asexual reproduction.
(C) Budding: Correct match is with ii Yeast, which reproduces by budding.
(D) Fragmentation: Correct match is with i Amoeba, which reproduces by fragmentation.
Step 3: Conclusion.
The correct matching is a-iii, b-iv, c-ii, d-i.
