What type of errors does ArithmeticError serve as the base class for?

Errors related to numeric calculation failures.

Errors related to invalid indexing or key lookups.

Errors related to type mismatches in operations.

Errors related to invalid argument values.

Why are abstract exception classes like LookupError not typically raised directly?

Because they are only used internally by the interpreter.

Because they are meant to serve as base classes for more specific exceptions.

Because they are deprecated and no longer supported.

Because they cannot be caught by except clauses.

When is the KeyboardInterrupt exception raised in Python?

When a keyboard input operation fails due to invalid input.

When the user presses Ctrl+C to interrupt the running program.
