Explanation:

• Option A (Investment banks) is correct because investment banks specialize in advising corporate clients and facilitating transactions, including seasoned securities offerings. A seasoned offering refers to the sale of additional units of a security that has already been issued by the issuer, also known as a secondary offering.

• Option B (Commercial banks) is incorrect. Commercial banks are depository institutions that primarily accept deposits and provide loans, along with transactional services like check writing. They do not typically engage in arranging securities offerings.

• Option C (Multilateral trading facilities) is incorrect. MTFs are trading venues that operate similarly to exchanges but lack regulatory authority over subscribers beyond their trading conduct within the system. They do not assist in securities offerings.
