Answer:
The correct answer is letter "A": The bank executive was pleased to be employed by a stable corporation.
Explanation:
Intensifiers are subjective expressions that allow readers to know how the speaker feels towards a certain topic. In business messages, intensifiers are unnecessary making segments to be wordy and giving them an unprofessional sound. Business writing must be objective, straight-to-the-point, avoiding hidden verbs and exuberance. Thus, the phrase:
The bank executive was quite pleased to be so definitely employed by a stable corporation;
sounds less exuberant by removing "so definitely". Then:
The bank executive was pleased to be employed by a stable corporation.
