[GMAT math practice question]
A jar contains 4 balls, labeled 1,2,3, and 4. A ball is selected from the jar, and its number is recorded before it is returned to the jar. If a second ball is then selected from the jar, what is the probability that the difference between the numbers on the two balls selected is 1?
\(A. \frac{1}{3}\)
\(B. \frac{3}{4}\)
\(C. \frac{1}{2}\)
\(D. \frac{5}{8}\)
\(E. \frac{3}{8}\)
