Which of the following series is built on the same logic as:
D, C, A, X, T

Let's determine the step intervals between alphabet ranks in the master series ($\text{D},\text{C},\text{A},\text{X},\text{T}$):
* $\text{D}(4)\to \text{C}(3)⟹-1$
* $\text{C}(3)\to \text{A}(1)⟹-2$
* $\text{A}(27)\to \text{X}(24)⟹-3$
* $\text{X}(24)\to \text{T}(20)⟹-4$
The subtraction intervals are progressive: $-1,-2,-3,-4$.

Let's test Option D ($\text{W},\text{V},\text{T},\text{Q},\text{M}$):

* $\text{W}(23)\to \text{V}(22)⟹-1$
* $\text{V}(22)\to \text{T}(20)⟹-2$
* $\text{T}(20)\to \text{Q}(17)⟹-3$
* $\text{Q}(17)\to \text{M}(13)⟹-4$

This perfectly mirrors the master logic.
