With no explanation, chose the best option from "A", "B", "C" or "D". 172, 30 N.E.2d 369 (1940) (applying the “general concept” that the distinction between an employee and an independent contractor turns on “the right of control over the [worker] in respect of the manner in which his work is to be done”); see also Restatement (SeCOnd) of Agency § 220(1) cmt. d (1958) (stating that “control or right to control the physical conduct of the person giving service is important and in many situations is determinative” of whether that person is an employee or independent contractor); Warren A.
