When you see the word or, it means one of those statements has to be true, and when you see the end, it means that one statement of each pair has to be true.
For the first, statement, either 9 has to be the largest digit or 4 has to be the smallest digit to make the statement true. 9 is larger that 4 and 3 so it is the largest, so this overall statement is true.
For the second statement, either the 3 has to be even or the 9 has to be odd. Even though 3 is not an even number, 9 is an odd number so the overall statement is true.
Therefore, the final answer is A. yes
Hope this helps.
