Suppose you buy a Delta-neutral straddle on a stock (i.e., you buy both a near-the-money call and a near-the-money put with the same time to maturities), and partially finance this purchase by selling a less expensive Delta-neutral strangle on the same underlying (i.e., you sell both an out-of the-money call and an out-of the-money put, with the same time-to-maturities as you used in the straddle you bought). Then your overall position:

	a.	Could have either a positive or negative Gamma.
	b.	Has a positive Gamma.
	c.	Has a negative Gamma.
	d.	Is Gamma-neutral
