I’m stuck on my three social studies questions.

They are asking:
1.why did Thomas Paine write the pamphlet, common sense?
2.what was most dangerous about signing the Declaration of Independence?
3.why did Jefferson list specific grievances against George the 3rd?

I picked
C
B
D
If anyone knows if I’m correct please reply I’m really desperate
(And yes I read through the whole thing.)

Yes, all of your answers are right, sorry I'm like two years late lmao. This is just for anyone else asking the same question I guess.
