In qualitative analysis, we use specific reagents to identify and separate different ions present in a mixture. In the case of Pb^2+, Ag^+, Cu^2+, and Cd^2+, we need to determine the common ions that can be identified using various reagents. Let's analyze each option to find the correct answer:

a) HCl and H2S:
- HCl (hydrochloric acid) is commonly used to identify the chloride ion (Cl^-). It forms a white precipitate with Ag^+ ions (AgCl) and a yellow precipitate with Pb^2+ ions (PbCl2). However, it does not react with Cu^2+ or Cd^2+ ions.
- H2S (hydrogen sulfide) is commonly used to identify the sulfide ion (S^2-). It forms a black precipitate with Pb^2+ ions (PbS) and a brown precipitate with Cd^2+ ions (CdS). However, it does not react with Ag^+ or Cu^2+ ions.
- Therefore, HCl and H2S do not furnish the common ions for these four ions.

b) NH4OH and NH4Cl:
- NH4OH (ammonium hydroxide) is commonly used to identify the hydroxide ion (OH^-). It forms a light blue precipitate with Cu^2+ ions (Cu(OH)2) and a yellow precipitate with Cd^2+ ions (Cd(OH)2). However, it does not react with Pb^2+ or Ag^+ ions.
- NH4Cl (ammonium chloride) does not furnish any common ions for these four ions.
- Therefore, NH4OH and NH4Cl do not furnish the common ions for these four ions.

c) Na2SO4 and H2S:
- Na2SO4 (sodium sulfate) is commonly used to identify the sulfate ion (SO4^2-). It forms a white precipitate with Pb^2+ ions (PbSO4) and a yellow precipitate with Ag^+ ions (Ag2SO4). However, it does not react with Cu^2+ or Cd^2+ ions.
- H2S (hydrogen sulfide) is commonly used to identify the sulfide ion (S^2-). It forms a black precipitate with Pb^2+ ions (PbS) and a brown precipitate with Cd^2+ ions (CdS). However, it does not react with Ag^+ or Cu^2+ ions.
- Therefore, Na2SO4 and H2S furnish the common ions for these four ions.

d) NH4OH and (NH4)2CO3:
- NH4OH (ammonium hydroxide) is commonly used to identify the hydroxide ion (OH^-). It forms a light blue precipitate with Cu^2+ ions (Cu(OH)2) and a yellow precipitate with Cd^2+ ions (Cd(OH)2). However, it does not react with Pb^2+ or Ag^+ ions.
- (NH4)2CO3 (ammonium carbonate) does not furnish any common ions for these four ions.
- Therefore, NH4OH and (NH4)2CO3 do not furnish the common ions for these four ions
