Explanation:

Step1: Identify valid numbers

We consider two - digit numbers in the range 01 - 90. Ignore numbers outside this range and repeated numbers.

Step2: Analyze given digits

From the sequence 06915 72954 10167 12142 26492, we take two - digit numbers one by one. 06 is valid. 91 is invalid (out of 01 - 90 range). 57 is valid. 29 is valid. 54 is valid. 10 is valid.

Answer:

A. 06, 57, 29, 54, 10
