For example, the words ‘hot’ and ‘cold’ are antonyms of each other, as they convey opposite meanings.
The word ‘urbane’ refers to ‘(of a person) courteous and refined in a manner’. This word is usually used as an adjective and another variant of this is ‘urban’. Another antonym of this word is ‘rural’. It was used in the sentence as an adjective describing the noun ‘attitude’. This means that the attitude has the manner of modernity. And, it is described as attracting friends, as the subject appeared friendly.
Now, we know the meaning and usage of the word ‘urbane’. Let’s look at our options:
(a)rude - The word ‘rude’ refers to ‘offensively impolite or bad-mannered'. This has a completely different meaning to the given word. It is not the required antonym. So, this is an incorrect option.
