Answer:
Shelf-registration
Step-by-step explanation:
'Shelf-registration' is illustrated as the process in which a company is permitted to issue and sell their securities publically through a single prospectus authorized by SEC and thus, without getting a separate prospectus for each issuance. It is an authorized process approved by Unite States Securities and Exchange Commission(SEC) under the head rule no. 415.
As per the given description, the arrangement formed by Zinc Corporation exemplifies 'shelf-registration' as it has acquired a 'single registration document'(master registration statement) from the SEC with their approval and due to which it is permitted to 'issue or sell their securities frequently' with mere a short-form statement update.
