The correct answer is
9

Digits Ascending Order Formation

First, identify the digits in the given number: 8, 1, 2, 7, 3, 6, 5.

Next, arrange these digits in ascending (smallest to largest) order:

1, 2, 3, 5, 6, 7, 8

The new number formed by these ordered digits is 1235678.

Key Digit Identification

Identify the second digit from the left in the new number (1235678). This digit is 2.

Identify the second digit from the right in the new number (1235678). This digit is 7.

Sum Calculation

Calculate the sum of the two identified digits:

Sum = (Second digit from left) + (Second digit from right)

Sum = $2 + 7$

Sum = $9$

The sum of the digits that are second from the left and second from the right in the new number is 9.
