Correct answer: D
Concept
A letter series may be governed by a visual property rather than by equal alphabetic gaps. First identify the property shared by every given capital letter, and then continue through the alphabet to the next letter with that property.
Application
The alphabet positions are A=1, B=2, D=4, O=15, P=16, and Q=17. Their gaps are not a regular numerical progression, so a shape-based rule should be tested.
In standard block capitals, A, B, D, O, P, and Q each contains at least one completely enclosed region.
Continuing alphabetically after Q, R is the next capital letter with a completely enclosed region, in its upper bowl.
Cross-check and contrast
T consists of a horizontal top bar and a vertical stem, forming an open shape.
S is a continuous curved stroke whose two ends remain open.
Z consists of two horizontal bars joined by a diagonal stroke, forming an open shape.
R has a vertical stem, an enclosed upper bowl, and a diagonal leg.
Therefore, the sequence is completed by R.
