A CPA was engaged by Jackson & Wilcox, a small retail partnership, to audit its financial statements. The CPA discovered that, because of other commitments, the engagement could not be completed on time. The CPA therefore unilaterally delegated the duty to Vincent, an equally competent CPA. Under these circumstances, which of the following is correct?
A. Jackson & Wilcox must accept the delegation if Vincent is equally competent.
B. The duty to perform the audit engagement is nondelegable, and Jackson & Wilcox need not accept Vincent as a substitute.
C. If Jackson & Wilcox refuses to accept Vincent because one of the partners personally dislikes Vincent, Jackson & Wilcox has breached the contract.
D. The duty to perform is delegable in that it is determined by an objective standard.
