Correct option is B
The correct interpretation of “gambit” aligns with options ii and iv.
· Gambit means a calculated move or strategy, often with some risk, intended to gain an advantage (चालाक योजना, जोखिम उठाकर फ़ायदा पाने की कोशिश).
· ii directly explains a pricing tactic — a classic gambit in business.
· iv is also a form of risky ploy — offering a prize to attract more customers.
· i and iii do not relate to “strategic action” but rather to consequences and complaints, hence incorrect.
