Answer:
B). Many pilots come to commercial airlines after having had military training.
Step-by-step explanation:
'Biased language' is demonstrated as the use of a language(words or phrases) that proposes a prejudiced or partial representation of an issue that excludes the other(people) or fails to consider them while reaching a conclusion or judgment. The authors are required to be unbiased and not include their personal opinions or perceptions while relating a text as it may hurt the sentiments of some groups.
In the given question, the option that exhibits a biased language is option B as it offers a prejudiced or biased conclusion 'many pilots come to commercial airlines after military training' which excludes the ones who do not join. Thus, it offers an unfair representation and hence, option B is the correct answer.
