The extension total for each item can be computed by multiplying the quantity by the unit price.

For option A, the extension total would be $320 (4 x $80) and the invoice total would be $320 + $11.95 = $331.95.
For option B, the extension total would be $383.97 (3.3 x $116.35) and the invoice total would be $383.97 + $11.95 = $395.92.
For option C, the extension total would be $373.89 (3.3 x $113.27) and the invoice total would be $373.89 + $11.95 = $385.84.
For option D, the extension total would be $426.4 (4 x $106.60) and the invoice total would be $426.4 + $11.95 = $438.35.

Therefore, option C has the correct extension total and invoice total. The extension totals for each item are:
- 11ebb7d6_6d95_cbfa_ad4c_bdfd8ae3815c_TB8285_11: $249.99 x 2 = $499.98
- 11ebb7d6_6d95_f30b_ad4c_ef511b5dfd03_TB8285_11: $799.99 x 1 = $799.99
- 11ebb7d6_6d95_f30c_ad4c_a5e29fd42f36_TB8285_11: $449.99 x 1 = $449.99
- 11ebb7d6_6d96_1a1d_ad4c_c55579f65e8a_TB8285_11: $129.99 x 4 = $519.96

Adding up all of the extension totals gives a subtotal of $2,269.92. Adding tax and shipping (not given in the question) would then give the invoice total. Since only choice C has the correct extension totals, it must be the best choice.
