Answer:

D. Scintillation counter  

Explanation:

DNA is usually labelled with radioactive phosphorus, which is a β emitter, so you need a device that can detect β particles.

A scintillation counter detects β particles because they emit a flash of light when they hit a phosphor. The device converts the flashes into electrical signals, amplifies then about a million times, and then counts them.

A, B, and C are wrong. They are all common laboratory equipment, but they can't detect radioactivity of any sort.
