The answer is 1: That is the best chocolate cake I have ever tasted.
A superlative adjective expresses the greatest amount or degree that a given descriptor can sustain. It usually is differentiated from a comparative adjective which only expresses a relative degree of a descriptor between two or more things. A superlative is then an absolute entity that expresses the greatest possible quality. In the answer above, the chocolate cake is the BEST cake, meaning there is no better cake.
