Effect : Guitar Strings go dead after few weeks of intense use

Cause: Dirt and oil and not changes in material properties.

What do we need to do help the classical guitarist's son?

for that we need options
so the question is closed

(A) Determining if a metal alloy is used to make the strings used by classical guitarists
(B) Determining whether classical guitarists make their strings go dead faster than do folk guitarists
(C) Determining whether identical lengths of string, of the same gauge, go dead at different rates when strung on various brands of guitars
(D) Determining whether a dead string and a new string produce different qualities of sound
(E) Determining whether smearing various substances on new guitar strings causes them to go dead

option E is the answer
The researcher tells us that dirt and oil rather than material properties of the string are responsible for strings to go dead and ques asks which investigation will evaluate the researcher hypothesis. and therefore if we apply various substances on the string and see the result then we will see what the substance working on the string.
