The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that "Synergids of the embryo sac also help in fertilization in Angiosperms." - **Explanation**: Synergids are specialized cells located in the embryo sac of flowering plants. They play a crucial role during fertilization by guiding the pollen tube to the egg cell. 2. **Analyzing the Reason**: The reason given is "Obturators of synergids attract the pollen tube." - **Explanation**: The obturator is a structure that helps guide the pollen tube towards the embryo sac, but it is not a part of the synergids. Instead, it is located outside the embryo sac. 3. **Evaluating the Truth of Assertion and Reason**: - **Assertion**: True. Synergids do assist in fertilization by facilitating the entry of the pollen tube and helping in the fusion of gametes. - **Reason**: False. The obturator is not part of the synergids; it is a separate structure that aids in attracting the pollen tube. 4. **Conclusion**: Since the assertion is true and the reason is false, the correct relationship is that the assertion is correct, but the reason does not correctly explain the assertion. 5. **Selecting the Correct Option**: Based on the analysis, the correct option is: - **Option C**: Assertion is correct, and Reason is wrong.
