8. Person A gives 20% of the marbles in a bag to Person B, then gives 10% of the remaining marbles to Person C, and finally gives 25% of the remaining marbles to Person D. What percentage of the marbles does Person A have left compared to the initial amount?
(A) $20 \%$
(B) $33 \frac{1}{3} \%$
(C) $38 \%$
(D) $45 \%$
(E) $54 \%$
8. E.

From the problem, we know that after A gives to B and C, 0.8 × 0.9 = 72% remains. After A gives another 25% of the remainder to D, 0.72 × 0.75 = 54% is left.
