Find the part of the given sentence that has an error in it. If there is no error, choose 'No error.'
Visitors to Chernobyl are advised not to touching the dogs.

Option (d) contains an error.
Explanation: The phrase "not to touching" is grammatically incorrect. In standard English, the infinitive "to" must always be followed by the base form of the verb. Here, "touching" is a gerund form, which is inappropriate after "to." The correct construction is "not to touch."
1. The infinitive form is used after verbs like "advised," which expresses recommendations or instructions.
2. "Not to" negates the infinitive verb, so "to touch" becomes "not to touch."
3. Grammatically, "touching" disrupts the flow and meaning of the sentence because gerunds and infinitives are not interchangeable in this context.
4. Hindi Explanation: "Touching" की जगह "to touch" का इस्तेमाल होना चाहिए। "Not to" के बाद हमेशा infinitive (verb का base form) आता है।
5. Corrected sentence: Visitors to Chernobyl are advised not to touch the dogs.
