Answer:
A). Failed to exercise due care.
Step-by-step explanation:
As per the given details, Bugle Corp. needs to prove that Dennis & Co. failed to exert the required care which it was supposed to exercise while auditing the financial statements of Stanley Corp. This failure led Bugle Corp. to suffer major losses and thus, they must be accountable for this loss under the general law as they ignored the potential hazards. Legally, this is unlawful as they were expected to ensure that these hazards must have addressed and told Bugle Corp. on time but since they failed, they are guilty of the crime. Hence, option A is the correct answer.
