Choose the sentence in which the modal has been used incorrectly:

The correct answer is Option (1) → Ishaan dare not to go near our neighbour’s barking dog.

Dare not + base verb:

• The given sentence says “dare not to go”.
• When “dare” is used as a modal with “not”, it takes the base verb (the simple form of the verb, like go, eat).
• No “to” comes between “dare not” and the verb, so “to” is wrong here.
• Corrected: Ishaan dare not go near our neighbour’s barking dog.

Why the Other Options are Incorrect?

Option 2: You had better not tell Dadi about the broken lamp before dinner. This sentence is correct. “Had better not” gives a strong warning and takes the base verb “tell”.

Option 3: The pilgrims would rather stay at the temple guest house than at a costly hotel. This sentence is correct. “Would rather ... than” shows what the pilgrims prefer and takes the base verb “stay”.

Option 4: Wet clothes should be hung in the sun, not in a dark corner. This sentence is correct. “Should be hung” is a modal in the passive: should be + past participle (V3).
