The adverb/noun '十分' (jūbun - enough / sufficient / satisfactory) means having plenty or enough of something (time, resources, quantity). Option 1 is correct: 'There is enough time, so you don't have to rush.' Option 2 is incorrect because a severe cold uses 'ひどい風邪' (severe cold), not '十分な風邪'. Option 3 is incorrect because being tall uses '背が高い' (tall), not '十分'. Option 4 is incorrect because a dictionary being comprehensive uses '詳しい' (detailed) or '役に立つ' (useful), not '十分'.
