If frequency increases and other factors cause SPL to vary inversely, SPL will:

Explanation:
When two quantities vary inversely, increasing one causes the other to decrease while the remaining factors stay the same. If frequency goes up and SPL varies inversely with frequency, SPL must fall. So the sound pressure level decreases as frequency increases. The other options don’t fit because they would require SPL to stay the same, rise, or change unpredictably despite the inverse relationship.
