KEY CONCEPT #1: Every factor of n is also a factor of 2n
So, EITHER n and 2n have the same number of prime factors OR 2n has more prime factors than n has.
In other words, the correct answer is either C or B
KEY CONCEPT #1: Since n is ODD, we can conclude that 2 (a prime number) is NOT a factor of n
Since 2n is EVEN, we can conclude that 2 IS a factor of 2n
Since 2 (a prime number) IS a factor of 2n but NOT a factor of n, we can see that 2n must have MORE prime factors than n has.
