Correct answer: A

Analyze Statement I

Statement I says: Nickel is being used as the catalyst for producing syn gas and edible fats.
- Edible fats: Nickel is indeed used as a catalyst in the hydrogenation of vegetable oils to convert them into vanaspati ghee / edible fats.
- Syn gas: Synthesis gas (syn gas, mainly CO + H $_2$ ) is generally produced using catalysts such as Ni in steam reforming of hydrocarbons, e.g. $\mathrm{CH_4 + H_2O \xrightarrow[high\ T]{Ni} CO + 3H_2}$
Therefore, Statement I is correct.
Analyze Statement II

Statement II says: Silicon forms both electron rich and electron deficient hydrides.
- Hydrides of silicon are called silanes.
- Silicon mainly forms compounds like SiH $_4$ , Si $_2$ H $_6$ , etc., which are electron-precise covalent hydrides.
- Unlike boron, silicon does not characteristically form both electron-rich and electron-deficient hydrides in the usual classification.
Therefore, Statement II is incorrect.
Match with options
- A: Statement I is correct but statement II is incorrect Correct
- B: Both correct Incorrect
- C: Both incorrect Incorrect
- D: Statement I incorrect but statement II correct Incorrect

Hence, the correct option is: $\boxed{A}$
