If h1, h2 and h3 are cascaded, and h1 = u(t), h2 = d(t) and h3 = d(t), find the overall impulse response

(a) s(t)

(b) d(t)

(c) u(t)

(d) all of the mentioned

I have been asked this question in an interview for job.

My question is from Continuous Time Convolution topic in portion Time-Domain Analysis of CT Systems of Signals and Systems

Correct choice is (c) u(t)

The best I can explain: The resultant impulse response will be the convolution of all the subsequent impulse responses.
