When It Comes to a Firm's Vision,mission,and Values,it Can Be

When it comes to a firm's vision,mission,and values,it can be said that:

A) Once instituted in the organization, the vision, mission, and values of a firm should be left alone, regardless of whether the company is successful or not.
B) New firms have to create these by using a driving vision to shape their mission and values, and existing firms should fine-tune their mission and values and reaffirm their values periodically.
C) New firms should modify their vision, mission, or values as they grow, but established firms should stick to what has worked in the past.
D) Existing firms should regularly discard their vision and mission in a renewal process.
