Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
A Universal Turing Machine simulates any other Turing Machine.
Theoretical results show that at least two internal states are required for universal computation.
Step 1: Recall UTM property.
A Universal TM must perform reading, writing, movement and simulation.
Step 2: Minimum state requirement.
One state is insufficient for universal computation. The minimum accepted answer is \[ 2 \] states.
Step 3: Write the answer.
Hence, \[ \boxed{2} \] is correct.
