Let $X = $ letters in "FOLLOW" and $Y = $ letters in "WOLF". Are $X$ and $Y$ equal?
AYes — both equal $\{F, O, L, W\}$
BNo — $X$ has more elements than $Y$
CNo — "FOLLOW" has 6 letters and "WOLF" has 4
DNo — $X$ has $L$ twice
Answer & Solution
Correct answer: A. Yes — both equal $\{F, O, L, W\}$
Letters in **FOLLOW** (distinct): $F, O, L, W$. Letters in **WOLF**: $W, O, L, F$. Both yield $\{F, O, L, W\}$.
Repetitions don't count and order doesn't matter — so the **sets** are equal even though the **words** have different letter counts.
