Answer:B
Diode–transistor logic (DTL) is the direct ancestor of _____________
A. Register-transistor logic B. Transistor–transistor logic C. High threshold logic D. Emitter Coupled Logic
Explanation: Diode–transistor logic (DTL) is a class of digital circuits that is the direct ancestor of transistor–transistor logic. To overcome the shortcomings of DTL, TTL came into existence.
