Which among the following is incorrect for o-machines?(a) Oracle Turin

1.	Which among the following is incorrect for o-machines?(a) Oracle Turing machines(b) Can be used to study decision problems(c) Visualizes Turing machine with a black box which is able to decide cerain decion problems in one operation(d) None of the mentionedI had been asked this question in an online quiz.The query is from The Language of Turing Machine topic in portion Introduction to Turing Machines of Automata Theory
Answer» The CORRECT choice is (d) None of the mentioned The best explanation: In AUTOMATA THEORY, an o- machine or oracle machine is a abstract machine used to study decision problems. The problem the oracle solves can be of any complexity class. EVEN UNDECIDABLE problems like halting problems can be used.
