Step 1: Identify Chatterjee’s motivation.
Chatterjee is motivated by his political standing and public image. The green policy comes from Bhowmick’s manifesto, but Chatterjee may adopt it if he believes it enhances his credibility. His clean image is central to his political identity.
Step 2: Evaluate each option.
(A) Asking for a deferment is practical, but it does not fundamentally convince Chatterjee not to pursue the policy; it only delays it.
(B) Strong argument — It appeals directly to Chatterjee’s electoral legitimacy. If he believes voters support him for his personal image rather than Bhowmick’s policy, he has no incentive to adopt the policy, making this highly persuasive.
(C) Warning of industry backlash appeals to fear, but Chatterjee is more concerned with public perception than industrialists’ approval.
(D) Sympathy appeals rarely work in politics, especially when broader public/environmental interest is invoked. Weak persuasion.
(E) A threat regarding political loyalty is confrontational and risks alienating Chatterjee further; least effective.
Step 3: Conclude.
The most convincing strategy is (B), as it directly links Chatterjee’s core strength (clean image) with voter support, thereby undermining the need to borrow Bhowmick’s policy.
