To convert from octal to hexadecimal, we can group the octal digits into sets of three, starting from the rightmost digit. We then replace each set of three digits with the corresponding hexadecimal digit.

In this case, 173 in octal is equivalent to the binary number 001 111 011.

We can then group the binary digits into sets of four, starting from the leftmost digit. We then replace each set of four digits with the corresponding hexadecimal digit.

0011 1101 in binary is equivalent to the hexadecimal value 3D, so the answer is B) 7B.
