Hello! I would love to help!
First let's identify the hypothesis and conclusion.
Hypothesis usually starts with "if" so the hypothesis of this statement is: An integer is a counting number.
The conclusion usually can be found by "then". So, the conclusion here is: It is zero.
So, let's evaluate the truth of these statements.
First, the hypothesis. An integer is a counting number. Yes, this is true because integers are counting numbers.
Now, the conclusion:
It is zero.
This is false because there are other integers as counting numbers that aren't zero: 2,3,4,5 for example.
So, therefore, the second answer is the correct one.
Hope this helped! Comment if you have questions!
