Everybody was astonished when he used such a profane language.

sacred
pure
profound
high

The correct answer is A. sacred.

Sacred means holy or connected with God or a god. Profane means disrespectful to God or a holy person or place.

B. pure means free from dirt or contamination. This does not make sense in the context of the sentence.

C. profound means having a great depth of meaning or significance. This does not make sense in the context of the sentence.

D. high means having a high level or degree. This does not make sense in the context of the sentence.

Here is an example of how the word “profane” can be used in a sentence:

“The man used profane language when he was angry.”
