Step 1: Understanding the Concept:
A person can only be shown to drive all five vehicles if the statements that mention them, combined, cover every one of the five: Motorcycle, Jeep, Lorry, Bus and Tempo.
Step 2: Key Formula or Approach:
Count how many separate statements mention each candidate, then combine the vehicles from all of them.
Step 3: Detailed Explanation:
R is named in three statements: Jeep and Lorry (with P), Motor Cycle and Lorry (with S and T), and Bus and Tempo (with T). Together these give R all five vehicles: Motorcycle, Jeep, Lorry, Bus and Tempo.
P is named in only two statements and never gets Bus or Tempo, so P covers just three of the five vehicles.
S is named in two statements, Motor Cycle and Lorry and Bus and Jeep, giving Motorcycle, Lorry, Bus and Jeep, but never Tempo, so S covers four of the five vehicles. T is named in two statements, Motor Cycle and Lorry and Bus and Tempo, giving Motorcycle, Lorry, Bus and Tempo, but never Jeep, so T also covers four of the five vehicles.
Step 4: Final Answer:
R is the only one whose combined profile covers all five vehicles.
