Correct Answer: Option C
Explanation

The hierarchy of data size is as follows:

Bit
Byte
Field
Record

A bit is the smallest unit of data and can represent a binary value of 0 or 1. A byte consists of 8 bits. A field is a collection of related data elements, and a record is a collection of fields. So, in terms of size, a byte is larger than a bit, and a field and a record are composed of multiple bytes and potentially multiple fields, respectively.
