If a, b, c are three sides of △ABC, then the result of simplifying |a-b-c||b-c-a||c-a-b| is () A.-a-b-c B. a+b+c C. a+b-c D. a-b+c

If a, b, c are three sides of △ABC, then the result of simplifying |a-b-c||b-c-a||c-a-b| is () A.-a-b-c B. a+b+c C. a+b-c D. a-b+c

A, b, c are the three sides of △ABC,
A < b+c, b < c+a, c < a+b,
A-b-c <0, b-c-a <0, c-a-b <0,
A-b-c||b-c-a||c-a-b|
=B+c-a+c+a-b+a+b-c
=A+b+c.
Therefore, B.

If a, b, c are three sides of △ABC, then the result of simplifying |a-b-c||b-c-a||c-a-b| is () A.-a-b-c B. a+b+c C. a+b-c D. a-b+c

A, b, c are the three sides of △ABC,
A < b+c, b < c+a, c < a+b,
A-b-c <0, b-c-a <0, c-a-b <0,
A-b-c||b-c-a||c-a-b|
=B+c-a+c+a-b+a+b-c
=A+b+c.
Therefore, B.
