If someone is described as contemptuous, their attitude is likely:

Describing someone as contemptuous indicates that they possess an attitude marked by disdain and scorn. This term arises from a feeling of superiority or disapproval towards others, often reflecting a belief that whatever they are observing is beneath their consideration or not worthy of respect. When a person is contemptuous, they directly express their negative feelings, often through dismissive comments or a condescending demeanor.

The other choices do not align with this definition. An attitude of neutrality suggests a lack of strong feelings or opinions, which contrasts sharply with the strong negative emotions implied by contempt. An attitude of comprehension indicates understanding and empathy, neither of which is present in a contemptuous disposition. Lastly, an attitude of admiration signifies positive regard and respect, which directly opposes the disdainful nature of being contemptuous. Therefore, the correct answer captures the essence of contemptuousness accurately with its emphasis on disdain and scorn.
