A Turing machine receives an input string longer than its tape. Which consequence follows for the machine's execution?

A)The computation halts immediately.
B)The machine enters an infinite loop.
C)The machine's tape expands dynamically.
D)The input string is truncated.

💡 Explanation

A Turing machine's tape has potentially infinite length; therefore, the tape will expand dynamically to accommodate the longer input because the computational model allows for indefinite tape extension, rather than halting or truncating the input.
