Question

*the best time to send your thank you note is:
1 week later
same day
within 30 minutes to 2 hours
no need to send a thank you email

Explanation:

In professional and etiquette contexts, sending a thank - you note (especially for things like interviews, professional interactions, or receiving a service) within 30 minutes to 2 hours is considered the best time as it shows prompt appreciation and keeps the interaction fresh in the recipient's mind. Sending it a week later or the same day (which is less prompt than the 30 min - 2h window) or not sending at all is not in line with good etiquette practices.

Answer:

C. Within 30 minutes to 2 hours
