Cause and Effect:\nI) Members of a community sat on a dharna (protest) demanding reservations in government jobs.\nII) The leaders of the movement from the community were arrested by the police.

Introduction / Context:
Public protests often lead to law-and-order action, including detention or arrest of leaders. We must identify the most plausible causal direction between the two presented events.

Given Data / Assumptions:

• I: A dharna was staged for reservations.
• II: Leaders were arrested.
• No contrary timeline is suggested.

Concept / Approach:
In standard reasoning items, a protest (I) plausibly precedes and causes police action (II). The reverse is unlikely, as arrests generally respond to, not cause, the already planned protest.

Step-by-Step Solution:
1) I → II: The demonstration likely triggered police response leading to arrests.2) II → I is implausible chronologically for the same protest; prior arrests could spark a future protest, but that is not indicated here.

Verification / Alternative check:
Administrative practice aligns with protests producing police action when required.

Why Other Options Are Wrong:
They invert or sever the intuitive sequence.

Common Pitfalls:
Assuming all arrests are pre-emptive; the stem implies consequence, not anticipation.

Final Answer:
If statement I is the cause and statement II is its effect
