Answer: The correct option is the first one: the quality of being unchanged from the original state.
Explanation:
Although each option corresponds with the definition of CRUDE, we have to remember that meaning is, in some way, contextual. This refers to the fact that a word can change its meaning according to with the sense of the sentence to which it belongs; thus, we can have, as in this case, <u>4 different meanings related to the same word.</u>
Specifically, in CRUDE, it is an adjective, which means that it is a word that has the function to qualify another word (it could be another adjective or a noun) and this is why all our options are quality.
In this sense, <u>the correct option is the first one: the quality of being unchanged from the original state. </u>We can say it because according to <u>LEXICO</u> (A dictionary powered by Oxford University) when a native speaker hears the word he or she thinks I the quality of being unchanged from the original state. Think, for example, in a vegetable that has been recently removed from the ground: it is crude.
<em>The second option: The quality of being primitive or uncultured </em>derives from the main definition because it is referring to someone that has not intellectual work done, so we can infer that has never been unchanged from the original state;<em> third and fourth options the quality of being obvious and the quality of being rough in execution </em>are more related to the characteristic of don’t have filter in saying or doing something; we say that someone is crude, for example, when this person doesn´t act politely or according to the social and cultural rules. Your friend could be crude if he tells you that you look fatter because probably is the truth, but he is not saying it tactfully.
