If a company changes working hours according to labour law which dimension is affecting it?

Correct answer: Legal dimension

The direct answer is option B: legal dimension. A labour law is an official rule made by the government or another lawful authority. If a company changes working hours because that law requires it, the company is responding to a legal condition in its business environment. Option A, economic dimension, relates to income, prices, interest, employment, and economic growth, not the stated source of the change. Option B is correct because the decisive words are labour law and compliance. Option C, social dimension, concerns social habits, education, population, and cultural expectations; a social preference is not given here. Option D, technological dimension, concerns machines, inventions, software, and production techniques, which are also absent. The same working-hour change could have social effects, but its stated cause is law, so legal is the best answer. Memory cue: law, act, rule, court, compliance, and regulation point to the legal dimension.
