Electrostatic Potential and Capacitance Part 2

A parallel plate capacitor was made with two rectangular plates, each with a length of I=3‌cm and breadth of b=1‌cm. The distance between the plates is 3µm. Out of the following, which are the ways to increase the capacitance by a factor of 10?
A. l=30‌cm,b=1‌cm,d=1µm
B. l=3‌cm,b=1‌cm,d=30µm
C. l=6‌cm,b=5‌cm,d=3µm
D. l=1‌cm,b=1‌cm,d=10µm
E. l=5‌cm,b=2‌cm,d=1µm
