Final answer:
There are 36 different types of shirts available from this company.
Step-by-step explanation:
To find the number of different types of shirts available from this company, we need to multiply the number of designs by the number of sleeve options and the number of color patterns. In this case, there are 3 designs, each with 2 sleeve options (short or long), and 6 color patterns. So, the number of different types of shirts is 3 x 2 x 6 = 36. Therefore, the correct answer is option (C) 36.
