Na imagem abaixo está representado um diagrama de fase de uma substância fictícia.

When the substance goes from state A to state C, there is a phase change from solid to liquid, which is called melting or fusion. Then, when it goes from state C to state B, there is another phase change from liquid to gas, which is called vaporization or evaporation.

Therefore, the correct answer is B) Sublima e condensa. This option is correct because the substance undergoes sublimation (going directly from solid to gas) and condensation (going from gas to liquid).

It's important to understand that the diagram shows the different states of matter and the transitions between them. The substance can change from solid to liquid (melting), from liquid to gas (vaporization), from solid to gas (sublimation), or from gas to liquid (condensation), and from liquid to solid (solidification or freezing).

In this case, the substance goes from state A (solid) to state C (liquid), which means it melts or fuses. Then, it goes from state C (liquid) to state B (gas), which means it vaporizes or evaporates. Therefore, the correct answer is B) Sublima e condensa.

It's worth noting that the other options are not correct because they do not describe the correct phase changes. Option A) Solidifica e vaporiza is incorrect because the substance does not solidify (go from liquid to solid) or vaporize (go from liquid to gas) in the described process. Option C) Fusão e solidifica is also incorrect because the substance does not fuse (go from solid to liquid) or solidify (go from liquid to solid) in the described process. Option D) Vaporiza e sublima is incorrect because the substance does not vaporize (go from liquid to gas) or sublimate (go from solid to gas) in the described process. Option E) Condensa e fusão is incorrect because the substance does not condense (go from gas to liquid) or fuse (go from solid to liquid) in the described process.
