Final answer:
To ensure an envelope is processed electronically, print the address using all capital letters, no punctuation, single spacing, and the company name first if applicable. The correct option is B.
Step-by-step explanation:
If you want an envelope to be processed electronically, you should primarily focus on the readability of automatic processing systems. To that end, you should print the address with a few key standards in mind: use all capital letters, avoid punctuation, use single spacing, and place the company name first followed by the Attention line if applicable.
However, in a professional business letter, the internal formatting would typically be single-spaced, with the sender's address at the top, followed by the date, inside address, greeting, body of the letter, closing, and your typed name and signature.
While electronic processing of mail might have specific requirements such as all capitals and no punctuation, standard professional communication and business letters will follow traditional grammar and formatting rules.
