Option C is the correct option as ‘application’ shows the intent of applying for the job. An application for employment, job application, or application form (often simply called an application) usually includes a form or collection of forms that an individual seeking employment, called an applicant, must fill out as part of the process of informing an employer of the applicant's availability and desire to be employed, and persuading the employer to offer the applicant employment.Option A cannot be used as ‘resignation’ means giving a formal statement of your intention to leave a job or position. Option B cannot be used as ‘resume’ means a person’s CV listing his or her personal and professional details. Option D cannot be used as ‘retirement’ indicates the period after one ceases to work.
