Choose the correct option from the words given below:

__________ child has to bring Rs. 500/- for the trip.

Each

The correct answer is Option (2) - Each

"Each" is used to refer to individual items or people within a group, emphasizing them one by one. In this context, it suggests that every individual child needs to bring Rs. 500/- for the trip. "Every" is similar, but "each" is more appropriate when referring to individual members of a group in this context.
