Give a regular expression for the languages - - 4 points - 2 points each L1 = {an bm : n< 4 and m≤ 3} L2 = {vwv : v, w ε {a, b}* and |v|≤3}

A) L1: (a{0,3}b{0,3}) L2: ((a|b){0,3}(a|b){0,3}(a|b)*)
B) L1: (a{0,3}b{0,3}) L2: ((a|b)*w(a|b)v(a|b))
C) L1: (a{1,4}b{1,4}) L2: ((a|b){0,3}(a|b){0,3})
D) L1: (a{1,4}b{1,4}) L2: ((a|b)*v(a|b)w(a|b))
