The response of the LTI system for \(\frac{d^2 y(t)}{dt^2} + \frac{dy(t)}{dt} + 5y(t) = \frac{dx(t)}{dt}\). Given that y(0–) = 2, \(\frac{dx(t)}{dt}\) (at t=0) = 0, x(t) = u(t) is __________

• A. 2e-t cos t u(t)
• B. 0.5 e-t sin t u(t)
• C. 2e-t cos t u(t) + 0.5 e-t sin t u(t)
• D. 0.5 e-t cos t u(t-1) + 2e-t sin t u(t-1)
