The correct answer is: A. the daughter.
The question is asking about the gender of the person who entered politics in 2003. The options are: A. the daughter, B. a daughter, C. daughter, and D. none of the above.
The only option that specifies the gender of the person is A. the daughter. This is the correct answer because it is the only option that is consistent with the information in the question. The question states that the person who entered politics in 2003 is the daughter of former information minister Nisar Memon. This information tells us that the person is female.
The other options are not consistent with the information in the question. Option B, a daughter, is not specific enough. It could refer to a daughter of any gender. Option C, daughter, is also not specific enough. It could refer to a daughter of any gender or to a female child in general. Option D, none of the above, is also not consistent with the information in the question. The question states that the person who entered politics in 2003 is the daughter of former information minister Nisar Memon. This information tells us that the person is female.
