Explanation:

To determine which hydroxide is precipitated by NH4OH containing NH4Cl, we need to consider the solubility rules for hydroxides.

Solubility Rules for Hydroxides:
1. Group 1 (alkali) metal hydroxides are soluble.
2. Ammonium hydroxide (NH4OH) is soluble.
3. Hydroxides of Group 2 (alkaline earth) metals are slightly soluble.
4. Hydroxides of transition metals and aluminum are insoluble.

Analysis of Hydroxides:
i) Zn(OH)2: Zinc hydroxide is insoluble according to solubility rules for hydroxides.
ii) Cr(OH)3: Chromium hydroxide is insoluble according to solubility rules for hydroxides.
iii) Mg(OH)2: Magnesium hydroxide is slightly soluble according to solubility rules for hydroxides.
iv) Al(OH)3: Aluminum hydroxide is insoluble according to solubility rules for hydroxides.

Precipitation Analysis:
NH4OH containing NH4Cl acts as a weak base due to the presence of NH4OH. When NH4OH is added to a solution containing the cations Zn2+, Cr3+, Mg2+, and Al3+, it forms insoluble hydroxide precipitates with the cations.

Conclusion:
Based on the solubility rules for hydroxides and the precipitation analysis, the hydroxides that are precipitated by NH4OH containing NH4Cl are:
- Zn(OH)2
- Cr(OH)3
- Mg(OH)2
- Al(OH)3

Therefore, the correct answer is option D) i, ii, iii, iv.
