(d) Direct delta function

I got this question in a national level competition.

My question is based upon The Impulse Function in division Signals and Systems Basics of Signals and Systems

Answer 1

Right answer is (a) Dirac delta function

Best explanation: The continuous time unit impulse function is also known as the Dirac delta function. This because it was first defined by Paul  Adrein Maurice Dirac as ∂(t)=0.
