I think the awnser to your question is C
We know, silicon is a natural semi-conductor, if manufacturer has lost its supplier then they can look for another element which is quite similar to silicon in electronic configuration.
We should go down the group, next element in 14th group is "Germanium" so we can use that for that purpose.
In short, Your Answer would be "Germanium"
Hope this helps!
The answer will be A.
