Which argument is an example of overgeneralization?

a. my german shepherd bit several family members before i got him a new collar, but has not since then. the new collar must have stopped him from biting.

b. i want to get a german shepherd as a pet, but my friends say that it is likely to bite me and won't be a good pet. i agree with them.

c. i was bitten by a german shepherd as a child, so i do not want to get a dog as a pet because it will bite me.

d. my german shepherd has bitten two people, so i have to send him to the pound or muzzle him.
anybody? ?

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
