In the question below, a statement is given followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested course of action logically follow (s) for pursuing. Statement: Tesla and its CEO Elon Musk have agreed to pay a total of $40 million and make a series of concessions to settle a government lawsuit alleging Musk duped investors with misleading statements about a proposed buyout of the company. The settlement with the Securities and Exchange Commission allows Musk to remain CEO of the electric car company but requires him to relinquish his role as chairman for at least three years.  Courses of action: I. Tesla must hire an independent chairman to oversee the company, something that should please a number of shareholders who have criticised Tesla's board for being too beholden to Musk.  II. The deal could remove one cloud that hangs over Tesla. Investors fretted about the company's ability to cope without Musk, a charismatic entrepreneur whose penchant for coming up with revolutionary ideas has drawn comparisons to one of Silicon Valley's most revered visionaries, Apple co-founder Steve Jobs.  III. Besides paying a fine and stripping Musk of his chairman's title, Tesla also must appoint two more directors who have no ties to the company or its management. Musk will be allowed to remain on the board.
