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