Final answer:
Thai is the most distant language from English in terms of linguistic distance. Therefore, the most appropriate option is E.
Step-by-step explanation:
Based on the information provided, the language that is most distant from English in terms of linguistic distance is Thai. Linguistic distance refers to how different two languages are from each other, taking into account factors such as grammar, vocabulary, and pronunciation. English is a member of the Germanic branch of the Indo-European language family, while Thai belongs to the Tai-Kadai language family. These two language families are not closely related, which is why Thai is considered the most distant from English in terms of linguistic distance. Other options listed in the question, such as French, German, Spanish, and Arabic, are all members of the Indo-European language family, albeit different branches within the family. Therefore, they are relatively closer to English compared to Thai.
