Which type of language shows gender bias in a job advertisement?

Correct answer: Hard technical work only for men

A job advertisement shows gender bias when it assumes that a type of work belongs only to one gender instead of judging applicants by relevant skills, training, and experience. Option C says that hard technical work is only for men. This excludes qualified women and other applicants before their abilities are even considered. The wording creates an unfair barrier and reinforces a stereotype that technical strength or competence is naturally male. Therefore, option C is the correct example of discriminatory language.

By contrast, saying that all qualified candidates may apply is inclusive, and asking for skills and experience uses job-related criteria. Mentioning a safe workplace describes a useful working condition but does not itself show gender bias. Fair recruitment should describe genuine duties and requirements without making unsupported assumptions about gender. If physical or technical abilities are necessary, the advertisement should specify measurable standards that apply equally to everyone. Thus the gender-based restriction in option C reduces equal opportunity.
