Without being licensed as an escrow officer, a broker may not handle escrow activities when they:

Option A is incorrect because representing the buyer is an agency function, not an escrow activity. A broker can represent a buyer without handling escrow functions, as their role remains that of an agent, not an escrow officer.

Option B is incorrect because representing the seller is also an agency function. While the broker facilitates the transaction, they don't assume escrow responsibilities unless specifically licensed as an escrow officer.

Option D is incorrect because if a broker is not involved in a transaction at all, they wouldn't be handling any escrow activities. The question specifically addresses when they may not handle escrow activities, not when they're uninvolved.
