Correct answer: D
To solve this problem, convert each number from its given base to the decimal system.
(A) (102)4 = 1 × 4² + 0 × 4¹ + 2 × 4⁰ = 16 + 0 + 2 = 18. (B) (10001)2 = 1 × 2⁴ + 0 × 2³ + 0 × 2² + 0 × 2¹ + 1 × 2⁰ = 16 + 1 = 17. (C) (103)6 = 1 × 6² + 0 × 6¹ + 3 × 6⁰ = 36 + 0 + 3 = 39. (D) (201)3 = 2 × 3² + 0 × 3¹ + 1 × 3⁰ = 18 + 0 + 1 = 19.
Comparing the decimal values: 17 < 18 < 19 < 39. Thus, the ascending order is B, A, D, C.
