The above asked question is from Electronic Injection System topic in portion Electronic Injection Systems of IC Engine

Answer 1

Correct option is (a) throttle position

Explanation: The throttle position sensor, senses the movement of the throttle plate so that the mixture flow can be adjusted for engine speed and acceleration while the manifold pressure sensor, monitors vacuum in the engine intake manifold so that the mixture strength can be adjusted with changes in engine load and the camshaft position sensor, senses rotation of engine camshaft for speed and timing of injection.
