Assertion :- Distribution of replicated chromosomes (DNA) to daughter nuclei by a complex series of events is almost accurate phenomenon.
Reason:- Such distribution of replicated chromosomes to daughter nuclei by a complex series of events is under genetic control.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false.

Answer

To analyze the given assertion and reason, let's break it down step by step:

### Step 1: Understand the Assertion
The assertion states that the distribution of replicated chromosomes (DNA) to daughter nuclei is an almost accurate phenomenon. This refers to the process during cell division (mitosis or meiosis) where chromosomes are evenly distributed to ensure that each daughter cell receives the correct number of chromosomes.

### Step 2: Understand the Reason
The reason provided states that this distribution is under genetic control. This implies that the mechanisms and processes that ensure accurate chromosome segregation during cell division are regulated by genetic factors, such as genes that code for proteins involved in the cell cycle.

### Step 3: Evaluate the Truth of Both Statements
- **Assertion**: True. The distribution of chromosomes during cell division is indeed a highly regulated and accurate process.
- **Reason**: True. The processes that govern chromosome distribution are controlled by various genes and regulatory mechanisms.

### Step 4: Determine the Relationship Between Assertion and Reason
Since both the assertion and reason are true, we need to determine if the reason correctly explains the assertion. The reason does explain why the assertion is true, as it highlights the genetic control behind the accurate distribution of chromosomes.

### Conclusion
Both the assertion and reason are true, and the reason is the correct explanation of the assertion. Therefore, the correct answer is that both statements are true, and the reason is the correct explanation of the assertion.
