Progenote is considered to be the more ancient form of life which gave rise to archaeobacteria and eubacteria.
Monomers are always multicellular.

Options

A. If both A and R are correct and R is correct explanation of A
B. If both A and R are correct but R is not correct explanation of A
C. If A is correct, R is wrong
D. If both A and R are wrong.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "Progenote is considered to be the more ancient form of life which gave rise to archaeobacteria and eubacteria."
- Progenotes are indeed considered primordial organisms, which are the earliest forms of life on Earth. They are believed to be the common ancestors of all prokaryotic life forms, including archaebacteria and eubacteria.

2. **Evaluating the Reason:**
- The reason states that "Monomers are always multicellular."
- Monomers are the basic building blocks of polymers, such as carbohydrates, proteins, and nucleic acids. They are typically single molecules and are not living entities. Therefore, this statement is incorrect because monomers are not multicellular; they are single units.

3. **Conclusion:**
- The assertion is true because progenotes are indeed ancient forms of life that gave rise to archaebacteria and eubacteria.
- The reason is false because monomers are not multicellular; they are single molecules.
- Therefore, the final conclusion is that the assertion is correct, but the reason is incorrect.

4. **Final Answer:**
- Assertion is true, Reason is false.
