d is the correct answer....if any one is getting 5 try to minimize the dfa but in that epsilon,a,b is also getting accepted...if i am wrong please correct me

If you are finding difficulty in getting dfa directly then draw nfa using regX. :
$(0+1)^*(00+11)$
then convert to equivalaeq dfa.

I guess it is possible only if language contains only one symbol.

NFA when converted to DFA gives us 5 states, and after minimization of the dfa the number states remain 5.

#TOC What will be the minimal DFA of this regular language?
Given L = { 0*1 + 0 + 1* + 10*1} where + symbol is UNION and NOT positive closure. Please draw the Minimal DFA for this.

What is the minimal DFA for this language (11+111)*, for Σ={0,1}.
What is the number of states for the above DFA,please draw NFA,DFA and minimised DFA for the same.Also won't the language not accept epsilon?
