Explanation:

Step1: Analyze the graph

The graph shows the value of US Dollar per Canadian Dollar over time (from 10/12 to 3/13). The y - axis is "Canadian Dollars per US Dollar" (wait, actually, the label is "Canadian Dollars per US Dollar"? Wait, no, the x - axis label is "Canadian Dollars per US Dollar" and y - axis is month. Wait, the vertical axis (y - axis) is the month, and the horizontal axis (x - axis) is "Canadian Dollars per US Dollar" (the number of Canadian dollars needed to buy one US dollar). In October 2012, one US dollar could buy about 0.98 Canadian dollars? Wait, no, the left text says "In October 2012, one US dollar could buy about 0.98 Canadian dollars." Wait, the graph's x - axis is "Canadian Dollars per US Dollar", so a higher value on the x - axis means more Canadian dollars per US dollar, i.e., the US dollar is stronger (since you need more Canadian dollars to buy one US dollar) or the Canadian dollar is weaker.

Step2: Evaluate the statements

• Statement 1: "The exchange rate remained unchanged from..." Let's check the graph. The graph has a line that changes over time (from 10/12 to 3/13), so the exchange rate is not unchanged. So this statement is false.
• Statement 2: "The US dollar grew stronger against the Canadian dollar from Oct 2012 to Jan 2013". Let's see the trend from Oct 2012 to Jan 2013. In Oct 2012, the value (Canadian dollars per US dollar) is around 0.98 (from the left text). As we move from Oct 2012 to Jan 2013, the x - axis value (Canadian dollars per US dollar) increases (the line goes up), which means that to buy one US dollar, you need more Canadian dollars. So the US dollar is getting stronger (since it costs more Canadian dollars to buy a US dollar) or the Canadian dollar is getting weaker. So this statement is true. Wait, but let's check the time period. Wait, the options in the top box: "Oct 2012 to Jan 2013", "Dec 2012 to Jan 2013", "Jan 2013 to Mar 2013". Wait, maybe the question is about which time period the US dollar grew stronger. Let's re - examine the graph. From Oct 2012 to Jan 2013, the line (value of US dollar in Canadian dollars) is increasing. From Jan 2013 to Mar 2013, the line is decreasing. From Dec 2012 to Jan 2013, there is a change, but the main growth is from Oct 2012 to Jan 2013. Wait, maybe the question is to identify the correct time period when the US dollar grew stronger. The graph shows that from Oct 2012 to Jan 2013, the number of Canadian dollars per US dollar increased, meaning the US dollar appreciated (grew stronger) against the Canadian dollar.

Answer:

The time period when the US dollar grew stronger against the Canadian dollar is "Oct 2012 to Jan 2013" (the first option in the top box).
