Question

a skull and crossbones pictogram indicates this kind of information about a chemical.
options:
gases under pressure
flammable
acute toxicity
irritant

Explanation:

The skull and crossbones pictogram is a standard hazard symbol indicating that a chemical has acute toxicity (can cause harmful or fatal effects if exposed to it acutely). "Gases under pressure" has a different pictogram, "Flammable" has a flame - like pictogram, and "Irritant" has a different symbol. So the correct option is related to acute toxicity.

Answer:

C. Acute Toxicity (assuming the options are labeled as A. Gases under pressure, B. Flammable, C. Acute Toxicity, D. Irritant. If the original option labels are different, adjust accordingly, but based on the content, the correct one is the option with "Acute Toxicity").
