Final answer:
The correct order of the four parts of a cover letter is heading, introduction, body, and closing.
Step-by-step explanation:
The correct order that the four parts of a cover letter should appear in is:
- Heading (your return address, date, inside address)
- Introduction (explanation of why you are writing the letter)

Remember to use a professional business font, single spacing with a double space between paragraphs, and to include your name and signature at the end of the letter.
