In option (a), the preposition 'since' does not require the preposition 'of' to follow it. The preposition 'of' can be removed to make the sentence error-free.
In option (c), an adjective is required to describe the state of 'seeing', so the use of the past participle form (V3) of the verb 'excited' is incorrect and the adjective 'exciting' is to be used.
In option (d), the adverb 'professionally' is incorrectly used to qualify the noun 'chef' instead of an adjective. Nouns can be qualified only by an adjective and instead of the adverb, the adjective form 'professional' is to be used.
Option (b) is a sentence that is grammatically and contextually correct without any errors.
Hence, the correct answer is option (b). Here, 'hides' means the skin of an animal that will be used for making leather, etc.
