Explanation:

Question 32

Suspension springs for bearing the axle: The helical type spring is commonly used as a suspension spring to bear the axle (stores energy, resists compression/extension). Torsion, laminated, rubber types have different uses (torsion for torque, laminated for heavy loads with less deflection, rubber for vibration damping). So helical type is correct.

Vehicle battery ion transfer: Electrolyte in a battery (like sulfuric acid - water mixture) allows ion flow for current. Distilled/pure water don't conduct ions, sulfuric acid alone is too strong. Electrolyte is the medium for ion transfer.

Clicking sound, engine no crank: Loose battery terminals cause poor electrical connection, leading to clicking (starter solenoid tries but no power). Clogged injector (fuel issue, no click), oxygen sensor (emissions, no start - click), faulty alternator (charging, not start - click). Loose terminals are common for this symptom.

Answer:

A. helical type
