I need it as soon as possible pls fast

Extracted text: A sound system consists on a CD player, cascaded to an amplifier and followed by speakers. Each of these three subsystems can be modelled by a transfer function as indicated in the figure below. The input of the sound system u(t) is the CD laser reader, and the output y(t) is the sound/acoustic pressure as shown on the graph. Which of the following options represents the sound at any given time t? u(t) CD player Amplifier Speaker U(s) U1(s) 1 U2(s) 1 Y(s) s+2 s+ 1 s2 +6s +34 O a. y(t) = -0.04 + 0.059t + 0.034e+ 0.005e 3cos(5t)- 0.0016e 3t sin(5t) O b. y(t) = -0.8t +0.098t + 0.045e Oc. y(t) = -0.04 + 0.059t + 0.034et +0.15e-3t cos(5t) – 0.016e-3t sin(5t) O d. y(t) = 0.04 + 0.059t + 0.034e 24 +0.005e-3t cos(-5t) – 0.0016e 3t sin(5t) + 0.18e 3t -0.016e 2t 1-adojs
