In a redox reaction, what role does the reducing agent play?

a- it gives up electrons
b- it keeps its electrons
c- it takes electrons
d- it takes oxygen atoms

The correct answer is Option A.

Explanation:

Reducing agent is defined as the agent which helps the other substance to get reduced and it itself gets oxidized. These agents undergo oxidation reaction.

Oxidation reactions are the reactions in which a substance looses its electrons to form a positive ion.

Hence, the correct answer is Option A.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
