Jess, a general contractor, is building a house. She hires Boris, an electrician, to do all the electrical work in the house for $17,000. Before Boris begins his work, he notifies Jess in writing that Jillian will be doing the electrical work instead. Jess does not respond. When Jillian fails to perform, Jess sues Boris. Boris is:

	a.	liable
	b.	liable but only if Boris agreed to remain responsible for the job
	c.	not liable because Jess failed to object to the delegation
	d.	not liable because Jess validly delegated her duties
