Correct answer: B
Concept
In digit-selection questions, first order the complete numbers as directed; only then select the required digit positions.
In a three-digit number abc, a is the first digit, b is the second digit, and c is the third digit.
Application
Arrange the numbers in descending order: 587 > 562 > 455 > 439 > 186. Thus, the second-highest number is 562 and the lowest number is 186.
The second digit of 562 is 6.
The third digit of 186 is 6.
Add the selected digits from left to right: 6 + 6 = 12.
Cross-check
Reading 562 as 5 | 6 | 2 and 186 as 1 | 8 | 6 confirms that the selected digits are 6 and 6; their sum is 12.
Therefore, the result is 12.
