(C) III only
(D) I and II only
(E) II and III only

Product of n consecutive integers = P
n >= 2
Since there are 2 or more terms, there is at least one even term => P is even
P can be negative (if n = 3 and all terms are negative), or positive (if all terms are positive), or 0 (if one of the consecutive terms is 0).
Hence, answer is A.

If P is the product of n consecutive integers, and n>=2
If the 3 consecutive integers are -3,-2 and -1, the product is not a positive number(III is out)
If the 2 consecutive integers are -1 and 0, the product is not an odd number(II is out)

However, P will always be an even number(Option A) as I is always true!

Since n >= 2, p must be even.
I is true.
II cannot be true, since n is even.
P can be positive or negative. Hence III is not true
Answer A - I only.

The Product of n consecutive integers equals to P and if n>=2, then P is always an even number.

So, answer options is A.

If P is the product of at least two consecutive integers, then at least 1 of the integers is even, and thus P must be even, so I is true. Furthermore, since P is even, it cannot be odd, so II is false. We also cannot say for sure whether P is positive. For example, if one of the integers is 0, then P = 0, which is not positive, so III is false.

P must be even, because in any three consecutive integers, there'll be at least one even number. Therefore it cannot be odd. Also, the product could be negative (-3,-2-1) or even zero.
