The u. s. house of representatives contains. a. 435 members and is considered more likely to represent local constituent interests. b. 435 members and is considered more stable and immune to passing popular whims. c. 100 members and is considered more likely to represent local constituent interests. d. 100 members and is considered more stable and immune to passing popular whims.

The US House of Representatives has 435 members (it's the senate that has 100 members), so we only consider the options that mention this:

a) 435 members and is considered more likely to represent local constituent interests.
b) 435 members and is considered more stable and immune to passing popular whims.

The better answer is a) since the representatives represent their states - so they're more likely to represent their local interests to gain a favour with their voters.
