Question

Which among the following cars are parked at the extreme ends?

• A. S, T
• B. X, Q
• C. X, S
• D. S, Q

Hint:

End–position constraints often become forced after placing the long-gap pairs; keep checking extremes after each placement.

Answer 1

The Correct Option is C

From the final lineup: \[ 1:\boxed{S}\ \cdots\ 7:\boxed{X}. \] Hence extremes are \(\boxed{X\ \text{and}\ S}\).
