Which of the following form part of the borders of almost all of the central american countries?
a. caribbean sea and mexico
b. caribbean sea and pacific ocean
c. north america and south america
d. pacific ocean and honduras

I believe the correct answer from the choices listed above is option B. IT is the caribbean sea and pacific ocean that form part of the borders of almost all of the central american countries.  Central America is bordered by Mexico to the north, Colombia to the southeast, the Caribbean Sea to the east, and the Pacific Ocean to the west. Hope this answers the question.
