Directions: Fill in the blank with appropriate word from the given options. A man who is well-bred & honorable invariably shows______ for the feeling of other people.

Consideration is correct. 'Shows consideration for' means demonstrates regard for others' feelings - this is exactly what a well-bred, honorable person does. Concern could work but consideration is more precise for thoughtful regard. Decaying is meaningless in context. 'None of these' is incorrect because consideration fits perfectly.
