1. The problem is to complete the sentence "Les croissants ____ grands." with the correct negative form in French. 2. The subject "Les croissants" is plural, so the verb must agree in number. 3. The correct negative form for plural subjects is "ne sont pas". 4. The sentence becomes: "Les croissants ne sont pas grands." 5. This means "The croissants are not big." 6. The other options are incorrect because: - "ne pas sont" is not a correct word order in French. - "n'est pas" is singular, not plural. - "sont pas ne" is an incorrect word order. Therefore, the correct answer is "ne sont pas".
