Explanation:
ASCII ( American Standard Code for Information Interchange) is a standardized one byte representation for characters.
For example, character 'a' has an ascii representation of 0x61.
'c' has a ascii representation of 0x63.
Converting the given hex representations to their respective characters using standard ascii tables, we get:
0x54 - T
0x68 - h
0x65 0x63 - e c
0x61 - a
0x6b - k
0x65 0x69 - e i
0x73 0x61 0x6c - s a l
0x69 - i
0x65 - e
