To determine which options are true for fermentation, we can break down each statement and analyze it:

1. Uses pyruvate to accept electrons: This statement is not true. In fermentation, pyruvate does not accept electrons.

2. Uses pyruvate to donate electrons: This statement is true. During fermentation, pyruvate donates its electrons to another molecule.

3. Regenerates NADH: This statement is not true. Fermentation regenerates NAD+ (nicotinamide adenine dinucleotide), not NADH.

4. Regenerates NAD+: This statement is true. Fermentation regenerates NAD+ so that glycolysis can continue. NAD+ is necessary for the conversion of NADH back into NAD+, allowing glycolysis to proceed.

5. Directly makes ATP: This statement is not true. Fermentation does not directly produce ATP; it is an anaerobic process that generates energy without requiring oxygen.

6. Allows glycolysis to continue in the cytoplasm making ATP: This statement is true. Fermentation allows glycolysis to continue by regenerating NAD+, which is necessary for the conversion of glyceraldehyde-3-phosphate into pyruvate. Glycolysis produces a small amount of ATP during this process.

7. Allows oxidative phosphorylation to continue in the mitochondria making ATP: This statement is not true. Fermentation is an alternative pathway when oxidative phosphorylation in the mitochondria is not possible due to a lack of oxygen.

8. Uses oxygen: This statement is not true. Fermentation is an anaerobic process, meaning it occurs in the absence of oxygen.

Based on the explanations above, the true statements for fermentation are:
- Uses pyruvate to donate electrons
- Regenerates NAD+
- Allows glycolysis to continue in the cytoplasm making ATP
