The correct answer is (3) Penicillium and Aspergillus

Step by step Explanation:

Reproduction in fungi occur in three forms: Vegetative, Asexual and sexual methods.

• VEGETATIVE REPRODUCTION- It includes methods lik hyphae, fission, budding, sclerotia, etc. In almost all of them they reproduce by diving or breaking themselves off.

• ASEXUAL REPRODUCTION: this takes place with the help of spores. They are either Endogenous or Exogenous spores. Endogenous spores are produced within sporangium example of endogenous spores are Mucor, Rhizopus. Exogenous spores are produce in conidia. They are externally branched or unbranched conidiophores. Example of Exogenous are Aspergillus and Penicillium.  

• SEXUAL REPRODUCTION: These are produce through mating. Two phases are found in their life cycle: haploid and diploid phase. Example are: Phycomycetes and Ascomycetes
