Please explain the answer shortly! :)
The language of the regular expression (0+10)* is the set of all strings of O's and 1's such that every 1 is immediately followed by a 0. Describe the complement of this language (with respect to the alphabet {0,1}) and identify in the list below the regular expression whose language is the complement of L((0+10)*). (0+1)*11(0+1)* (1+01)* (0+11)* (0+1)*1(8+1(0+1)*)
