If the length of \( \operatorname{rod} \mathrm{A} \) is \( 3.25 \pm 0.01 \mathrm{~cm} \) and that of \( \operatorname{rod} \mathrm{B} \) is \( 4.19 \pm 0.01 \mathrm{~cm} \), then the rod B is longer than rod A by:
a. \( 0.94 \pm 0.00 \mathrm{~cm} \)
b. \( 0.94 \pm 0.01 \mathrm{~cm} \)
c. \( 0.94 \pm 0.02 \mathrm{~cm} \)
d. \( 0.94 \pm 0.005 \mathrm{~cm} \)
