Answer:
Option A. The weakness in the sentence is that the candidate appears to be selfish.
Step-by-step explanation:
When writing a sample cover letter in order to send it with your resume for an open position, it is important to give a good first impression to your possible new employer. When the author writes that "when i saw how much this position paid, I knew that I needed to get this job!" the person is not giving a positive image of themselves, as the employer can read that sentence and think that the candidate appears to be selfish, only thinking what he/she can gain for doing the work, and not what can they give to the job and/or company. Although salary is an important part when considering a new job, it should not be the main reason why you want to work somewhere, or if it is, the candidate should not express it so openly to the employer, as it gives a bad impression.
