Answer:B) Technician B 
Explanation:ECT(ENGINE COOLANT TEMPERATURE) is a sensor present in the coolant Temperature sensor that checks and transmits the Temperature to the ECM(engine control module). This helps to regulate the fueling time, speed and other factors that can impact the Temperature of the engine.
Stepped ECT circuits require different Internal resistance inside the PCM(power-train control module) is a combined control which includes the ECU(ENGINE CONTROL UNIT) AND TCU(TRANSMISSION CONTROL UNIT). The same sensor can be used for both the stepped circuit and a circuit that is not stepped.

The reason is none other than,
→ Prokaryotes are commonly referred as most primitive organisms
They lacks membrane - bound organelles , they are unicellular organisms who does not posses a true nucleus . 
→ Eukaryotes are most likely advanced organisms , they posses a true nucleus & membrane - bound organelles as well. There are unicellular & multicellular eukaryotes 
eg : Unicellular eukaryotes like Protists
