B) I2 (s) is a stronger oxidizing agent than Al3 (aq), and Al (s) is a stronger reducing agent than I - (aq).

Explanation:

An oxidizing agent accepts electrons in a redox reaction and become reduced while a reducing agent looses electrons and become oxidized.

Hence in a redox reaction, oxidizing agents are reduced while reducing agents are oxidized.

Looking at I2 and Al3+, I2 is a better oxidizing agent since it has a reduction potential of + 0.54V compared to - 1.66V for Al3+.

Given the statements above, the converse must be true, that is; All is a better reducing agent compared to I-
