Correct option is C
Option (c) is the correct order of the given sentences PQRS.
· After 1, the most immediate human reaction is P (People ran to shelters)—a quick, natural response to sudden rain.
· Next, Q (Water collected on roads) shows the physical consequence of continued rain; this typically follows once rain sustains.
· R (Traffic moved slowly) logically follows Q because accumulated water causes slow traffic; thus Q → R is a clear cause–effect chain.
· S (Many opened their umbrellas) rounds out the scene with another visible response and smoothly leads to 6 (It was a heavy shower)—the proliferation of umbrellas underlines the intensity of the rain.
· Hence, the coherent narrative is: 1 – P – Q – R – S – 6.
