To find the number of combinations of two-digit numbers having 8 can be made from the given numbers, we need to count how many times 8 appears in the set of numbers and how many numbers can be combined with 8 to form two-digit numbers.
In the set of numbers {8, 5, 2, 1, 7, 6}, 8 appears only once. We can combine 8 with any of the other 5 numbers in the set {5, 2, 1, 7, 6} to form two-digit numbers. Therefore, there are 5 possible combinations of two-digit numbers having 8 that can be made from the given set of numbers: 85, 82, 81, 87, and 86.
Therefore, the correct answer is option D: 11.

Solution:
To form a two-digit number with 8, we need to fix 8 at tens place and any of the given numbers (except 8) at units place. So, the required combinations are:

Therefore, the number of combinations of two-digit numbers having 8 that can be made from the given numbers is 6.
Hence, the correct option is (b) 6.
