Answer: B.
0 < a_2 < a_1

Step-by-step explanation:

The coefficients tacked onto the trig functions tell us how vertically stretched the curves are. The dashed curve, representing
y_1(t), is taller than the solid curve. Therefore
a_1 must be larger than
a_2

For the sine curve, note how it is increasing after we pass through t = 0. This indicates we have
a_1 as a positive number. The value of
a_2 is positive because the point (0,k) on the cosine curve has k being positive.
