What best describes the law of one price as it relates to the fixed income market?

		Each security in the market will always be priced at the same discount rate
		Market prices on securities of the same risk will be priced the same since market participants will quickly trade away any arbitrage opportunities
		Market prices will be the same regardless of the riskiness of each security. What's most important is the time to maturity and the relative prices.
		Each security can be bought and sold at only one price at any given time.
