**Question:**
Which is/are the major product(s) formed from the reaction of 1,2-dimethylcyclohexene with H₂/Pt?

**Diagram Explanation:**

The image consists of four structural formulas labeled I, II, III, and IV. Each represents a different stereochemical outcome of hydrogenation on a cyclohexane ring:

- **Structure I** shows a cyclohexane ring with two methyl groups (CH₃) on the top and bottom face, directly opposite each other, each with a hydrogen atom (H) also on the same carbon atom but oriented in the opposite direction.

- **Structure II** also depicts a cyclohexane ring wherein one methyl group and one hydrogen atom are on opposite sides of the plane. The second methyl group and hydrogen atom are positioned similarly to the first pair.

- **Structure III** has two methyl groups on the same side of the ring, with each hydrogen atom in different orientations on the adjacent carbons.

- **Structure IV** displays a cyclohexane ring with one methyl group pointing upwards and one hydrogen atom also pointing upwards from the same carbon, while the other methyl group points downwards.

**Options:**
- I
- II
- III
- IV
