The energy band diagrams for three semiconductor samples of silicon are as shown. We can then assert that [Haryana CEE 1996]

Sample X is undoped while samples Y and Z have been doped with a third group and a fifth group impurity respectively

Sample X is undoped while both samples Y and Z have been doped with a fifth group impurity

Sample X has been doped with equal amounts of third and fifth group impurities while samples Y and Z are undoped

Sample X is undoped while samples Y and Z have been doped with a fifth group and a third group impurity respectively
