Questions: 12. Writing a letter of application is often an important part of applying for jobs A. online. B. in person. C. indirectly. D. by phone.

The answer is A. online.

Writing a letter of application is commonly associated with online job applications. In today's digital age, many job applications are submitted through online platforms, where applicants are often required to upload a cover letter or letter of application along with their resume.

While applying for jobs in person might involve submitting a resume or filling out an application form, it is less common to submit a formal letter of application in this context. In-person applications might involve more direct communication or interviews.

Applying for jobs indirectly does not typically involve writing a letter of application. Indirect applications might involve networking or referrals, where a formal letter may not be necessary.

Applying for jobs by phone usually involves verbal communication rather than written documents. A letter of application is not typically used in this method of job application.
