Bconcentrations of explosive gas

Dall of the above
AI Explanation
The correct answer is C) an oxygen deficiency in a space. An oxygen indicator is a device designed to detect and measure the concentration of oxygen in a given space. It is primarily used to identify oxygen-deficient atmospheres, which can pose a serious health hazard. Oxygen-deficient environments can occur due to various reasons, such as the displacement of oxygen by other gases or the consumption of oxygen through chemical reactions. The other answer choices are incorrect because an oxygen indicator is not designed to detect the presence of carbon monoxide (option A) or concentrations of explosive gas (option B). These are separate types of gas detectors with different sensing mechanisms.
