Teacher:In this task, you are given a context and four options. Each option is a suggested ending for the context. You should read the context and pick the best ending for the context. Please answer with "A", "B", "C", and "D". 
Teacher: Now, understand the problem? Solve this instance: [header] How to multiply fractions [title] Write out the problem. [step] The two fractions should be written down so that their numerators are aligned with their denominators. [substeps] Ex : 2/4 * 2/4 [title] Multiply the numerators of the two fractions. <sep> (A) [substeps] Ex : 2/4 * 3/4 + 1 = 44 [title] Divide the two fractions. [step] The simple addition of the numerator and denominator gives the fraction 34. (B) [step] There should be a sum of the denominators of both fractions equal to 2. A formula to start is : [substeps] 1/(1/1=1/2), (2/1=1 , 2/1=2). (C) [step] The numerators of the two fractions should follow the same sequence of denominators. [title] Divide the numerators of both fractions by the denominators of both fractions. (D) [step] Since the numerators are both 2, you can multiply 2 * 2 to get 4. [title] Multiply the denominators of the two fractions.
