Question

to protect consumers, the sec requires brokers and dealers to information about securities. reveal regulate protect conceal

Explanation:

To protect consumers, the SEC (Securities and Exchange Commission) would require brokers and dealers to make information about securities known. "Reveal" means to make known or disclose, which fits the context of providing information to protect consumers. "Regulate" is about controlling or managing, "protect" is the goal here not the action on information, and "conceal" means to hide, which is the opposite of what's needed.

Answer:

A. reveal
