The string WWR is not recognized by any FSM because _____________(a) A

1.	The string WWR is not recognized by any FSM because _____________(a) An FSM cannot remember arbitrarily large amount of information(b) An FSM cannot fix the midpoint(c) An FSM cannot match W with WR(d) An FSM cannot remember first and last inputsI have been asked this question in exam.Query is from Finite Automata in chapter Finite Automata and Regular Expression of Compiler
Answer» The correct CHOICE is (b) An FSM cannot FIX the midpoint To elaborate: Palindromes cannot be RECOGNIZED by FSM.
