The correct answer is B. NO (nitric oxide).

Nitric oxide (NO) can act as both a reducing agent and an oxidizing agent in different reactions:

Reducing agent towards chlorine: NO can reduce chlorine gas (Cl2) to hydrochloric acid (HCl) according to the reaction:
2NO
+
Cl
2
→
2NOCl
2NO+Cl
2
​
→2NOCl

Oxidizing agent toward hydrogen sulfide: NO can oxidize hydrogen sulfide gas (H2S) to sulfur (S) according to the reaction:
4NO
+
H
2
S
→
4NO
+
2H
2
O
+
3S
4NO+H
2
​
S→4NO+2H
2
​
O+3S

Therefore, NO fits the description given in the question.
