The reducing power of alkali metals in comparison to halogens is

a) high

b) low

c) the same

d) nearly same

The answer is: a) High
Alkali metals are strong reducing agents whereas halogens are strong oxidizing agents.
This is because alkali metals tend to lose electrons in order to attain the noble gas configuration of their nearest noble gas.
By losing electrons they undergo oxidation and in the process reduce the other species. Whereas halogens gain an electron to attain their nearest noble gas configuration. This is why they are good oxidizing agents.
