The prefix "octa-" indicates 8 carbons, "diene" indicates two double bonds, and "yne" indicates one triple bond. The numbering should start at the end closest to the triple bond, giving the substituents at positions 1 and 6. The correct structure should have a triple bond between carbons 1 and 8, double bonds between carbons 3 and 4 and between carbons 6 and 7, and single bonds for all other carbons. The correct structure is represented by choice C.
