Which of the following statements is true?
a) If single measurements on identically prepared systems giveidentical results, the system is in the eigenfunction correspondingto the measured eigenvalue.
b) If a system is in a superposition state, a single measurement onidentically prepared systems will always give the sameresult.
c) If a system is in a superposition state, a single measurement onidentically prepared systems will give any one of the possibleeigenvalues with equal probability.
d) If a system is in an eigenstate of the operator corresponding tothe property being measured, successive measurements on the systemwill give identical results.
