The correct answer is A. It is a decimal that does terminate.
A rational number is defined as a number that can be expressed as the ratio of two integers a/b, where b is not equal to 0. Any decimal number that terminates can be written as a ratio of two integers since the decimal representation ends after a finite number of digits. In the given sequence 0.747447444744447444447..., the decimal representation does not go on indefinitely, but eventually repeats the sequence 74744. Therefore, it terminates and can be expressed as a rational number.
