Correct answer: (B) i-c, ii-a, iii-d, iv-b

Explanation

Peer-interaction in a racially mixed classroom is best studied ethnographically, matching i with c.

The developmental pattern of intelligence across age groups suits a cross-sectional survey, matching ii with a.

Testing the effect of television viewing on Science achievement is an experimental design, matching iii with d.

Studying the impact of an already-received education on social status is ex-post facto research, matching iv with b.

Pairings that send ethnography to the achievement study or an experiment to the classroom misread the data-gathering logic.

Ex-post facto research examines causes after effects have already occurred, without manipulating the variable.
