The correct answer is A — Counterfeit Currency. Financial Institution Bond Standard Form No. 24 is designed for commercial banks and similar financial institutions and incorporates a series of fundamental crime-related insuring agreements. Standard coverage includes fidelity, loss on premises, property in transit, forgery or alteration, securities exposures, and counterfeit currency protection. The counterfeit-currency insuring agreement covers qualifying direct loss resulting from the institution's good-faith receipt of counterfeit money.
The Series 17-70 outline specifically requires knowledge of Financial Institution Bonds, including Forms 14, 15, 23, 24, and 25 and their major insuring agreements.
Computer systems fraud can be insured through specialized crime/computer-fraud coverage or riders but is not the basic Standard Form No. 24 coverage intended by this question. Audit and claims expense is also generally an additional or specialized expense protection rather than one of the fundamental basic insuring agreements. Debit or credit card losses are subject to specialized provisions, exclusions, and optional coverages rather than constituting the basic answer.
The distinction is important: a financial institution bond is a package of fidelity/crime protections, but not every modern electronic-financial exposure is automatically within its basic form.
Therefore, A — Counterfeit Currency is correct.
