Explanation

'Incensed' means very angry. In such a context we usually use preposition 'at'.

The words at, in, of, on and to are examples of prepositions. A word such as a noun, pronoun or gerund following a preposition is said to be the object of the preposition. There are many 'small words' in English such as up, down, and by which we call prepositions. A preposition must have an object (a noun or a pronoun), so it is always related to a noun: across the road, over the wall, up the hill, down the mountain.
