Final answer:
A corporation sole cannot register to conduct real estate transactions as it is not meant for regular business activities.
Step-by-step explanation:
Among the business forms listed, a corporation sole is typically unable to register to conduct real estate transactions. A corporation for profit, not for profit, and a limited partnership can all potentially be registered to conduct such businesses, given they comply with relevant state and national laws. A corporation sole is usually associated with a religious leader and is not established for the purposes of conducting regular business transactions, such as those in real estate.
