Q. Which of the following is an integer?\newlineChoices:\newline(A) 9.419.41\newline(B) 66\newline(C) 8.168.16\newline(D) Ο€\pi
  1. Understand Integer Definition: Understand the definition of an integer. An integer is a whole number that can be positive, negative, or zero, but it cannot have any fractional or decimal part.
  2. Evaluate Choices: Evaluate each choice to determine if it is an integer.\newline(A) 9.419.41 has a decimal part, so it is not an integer.
  3. Continue Evaluating: Continue evaluating the choices.\newline(B) 66 has no decimal part and is a whole number, so it is an integer.
  4. Check Remaining Choices: Check the remaining choices even though we have already found an integer.\newline(C) 8.168.16 has a decimal part, so it is not an integer.\newline(D) Ο€\pi (pi) is an irrational number and not an integer.
  5. Conclude Integer Choice: Conclude which choice is an integer.\newlineFrom the evaluation, only choice (B) 66 is an integer.
