**Explanation:**
To determine the correct statement regarding compound X, let's analyze the given information step by step.
**1. Compound X gives effervescence with NaH.**
Effervescence with NaH indicates the presence of an acidic proton in compound X. This suggests that compound X contains a hydroxyl group (-OH).
**2. Treatment of X with acidic CrO3 solution turns the solution blue-green and forms C5H10O2.**
The reaction of compound X with acidic CrO3 is a common test for the presence of a double bond. The formation of C5H10O2 suggests that compound X contains a double bond, and the CrO3 oxidation has converted the double bond into a carbonyl group.
**3. Compound X can be resolved into enantiomers.**
Resolution of a compound into enantiomers indicates the presence of a chiral center. A chiral center is a carbon atom bonded to four different groups. In the case of compound X, it must contain at least one carbon atom with four different substituents.
Now, let's analyze each option based on the given information:
**a) It is 2-pentanol**
2-Pentanol has the molecular formula C5H12O, which matches the molecular formula of compound X. However, 2-pentanol does not contain a double bond or a chiral center. Therefore, option a) is incorrect.
**b) It is 3-pentanol**
3-Pentanol also has the molecular formula C5H12O, but it lacks a double bond and a chiral center. Therefore, option b) is incorrect.
**c) With HBr, it gives an achiral alkyl bromide**
This statement suggests that compound X does not contain a chiral center, as an achiral alkyl bromide does not have a chiral center. This matches the given information that compound X can be resolved into enantiomers. Therefore, option c) is correct.
**d) The oxidation product C5H10O2 is achiral**
The formation of a chiral compound from compound X indicates that compound X itself must contain a chiral center. Therefore, the oxidation product C5H10O2 cannot be achiral. Therefore, option d) is incorrect.
In conclusion, the correct statement regarding compound X is option c) - "With HBr, it gives an achiral alkyl bromide."
