Explanation:
The following features must contain a well-specified algorithm:
Description Exact measures described
Effective computation contains steps that a computer may perform
finitude It must finish algorithm.
In choice "a", there is little algorithm Because it does not stop, finiteness has already been incomplete. There is also no algorithm.
In choice "b", it needs productivity and computational burden. because it's not Enter whatever the end would be.
In choice "c", the algorithm is given the procedure. It fulfills all 3 algorithmic properties.
In choice "d", each algorithm is a defined process. Since it needs finitude.
