According to the Text, Research on Sentencing Disparity Using Two

According to the text, research on sentencing disparity using two different methods found:

A) experimental simulations have lower rates of sentencing disparity than actual case outcomes.
B) studies using experimental simulations as well as studies using case archival data both have mixed results.
C) data mined from archived cases revealed lower rates of sentencing disparity than simulated studies.
D) results from both experimental simulations and archived cases consistently reflected sentencing disparity.
