If h1, h2 and h3 are cascaded, and h1 = u(t+4), h2 = d(t-3) and h3 = d(t-5), find the overall impulse response

(a) u(t-4)

(b) u(t-6)

(c) u(t-8)

(d) all of the mentioned

The question was posed to me by my college professor while I was bunking the class.

This is a very interesting question from Continuous Time Convolution in section Time-Domain Analysis of CT Systems of Signals and Systems

The correct option is (a) u(t-4)

To elaborate: The resultant impulse response will be the convolution of all the subsequent impulse responses.
