[A]. 100

[B]. 166

[C]. 145

[D]. 128

✅ The correct answer is option D.
Go on subtracting 24, 21, 18, 15, 12, 9 from the numbers to get the next number.
190 – 24 = 166
166 – 21 = 145
145 – 18 = 127 [Here, 128 is placed instead of 127]
127 – 15 = 112
112 – 12 = 100 … and so on.

Therefore, 128 is wrong.
