The subject is 'chef' (singular, third person). In the Present Simple tense, singular subjects require the third person singular form of the verb. The suffix '-es' is added to verbs ending in 'o', 's', 'x', 'sh', 'ch'. For other verbs ending in 'y' after a consonant, 'y' is changed to 'i' and '-es' is added, but for verbs ending in 'y' after a vowel, just add '-s'. However, the option is 'loves'.
Therefore, the correct answer is 'loves'.
Answer: b) loves
