20. Yeast are:

• A. Hyphal unicellular fungi
• B. Non-Hyphal unicellular fungi
• C. Hyphal multicellular fungi
• D. Non-Hyphal multicellular fungi
• E. All are incorrect

Explanation: Yeast are typically oval or spherical in shape and reproduce through budding, where a small outgrowth or bud forms on the parent cell and eventually separates to become a new individual. This mode of reproduction is characteristic of unicellular fungi.
