[A]: There is no phenomenon like organic evolution.
[R]: Evolutior, is a discontinuous period

Options

A. If both A and R are true and R is the correct explanation of A
B. If both A and R are true but R is not the correct explanation of A
C. If A is true and R is false
D. If both A and R are false

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion (A)**: The assertion states, "There is no phenomenon like organic evolution." This implies a denial of the existence of organic evolution as a biological process.

2. **Understanding the Reason (R)**: The reason provided is, "Evolution is a discontinuous period." This suggests that evolution occurs in distinct phases rather than continuously.

3. **Evaluating the Assertion**: To evaluate the assertion, we need to consider the scientific consensus on organic evolution. Organic evolution is a well-documented phenomenon supported by extensive evidence from various fields such as genetics, paleontology, and comparative anatomy. Therefore, the assertion is false.

4. **Evaluating the Reason**: The reason states that evolution is a discontinuous period. In biological terms, evolution is generally understood as a continuous process of change over time, although it can include periods of rapid change (punctuated equilibrium). Thus, this statement can also be considered misleading or false.

5. **Conclusion**: Since both the assertion and the reason are false, the correct response to the question is that neither statement is true.
