When two variables move in the same direction, i.e., when one variable increases, the other variable also increases, the curve relating them will be upward sloping. This is known as a positive relationship or positive correlation. Hence, option A is the correct answer. Option B is incorrect because upward-sloping curves represent positive relationships, not negative relationships. Downward-sloping curves represent negative relationships, as in option C and option D, when the variables move in opposite directions.
