    If a and b are integers and the sum of ab and b is even, which of the following could be true?Ⅰ. a and b are both odd.Ⅱ. a is even and b is odd.Ⅲ. a is odd and b is even.
    A

    Ⅰand Ⅲ


    正确答案： C
    解析：
    Plug-in. StatementⅠ：if a and b are both odd, says a=1 and b=3, then ab+b=6. Since the sum is even, statementⅠ is true. StatementⅡ：1et a=2 and b=3, then ab+b=9. Since the sum is odd, this statement is false. Statement Ⅲ：let a=3 and b=2, then ab+b=8, which is even. So both statement Ⅰand statementⅢ are true.
