Answer:
An element
Elements are substances that cannot be broken down into simpler substances either by physical or chemical method.
Answer is A - HCl is the titrant and D-NaOH is the analyte.
In a titration process, the solution of unknown concentration considered is the analyte. During titration, a standard solution(titrant) is added to an analyte until the equivalence point is achieved.
So in this case as the concentration of NaOH is not known,NaOH is the analyte.
Titrant is the solution whose concentration is known to us and is added to an analyte until the equivalence point is reached. In this case since we know the concentration of HCl, HCl is the titrant.
