Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The rule is based on the number of letters in the month multiplied by 2. April (5 letters) = 10; May (3 letters) = 6 (though the prompt says 5, suggesting a different rule). If the rule is letters * 2.5: April (5*2.5=12.5) doesn't fit. If the rule is simply (Letters * 2.5) rounded, July (4 letters) would be 10.
