Late seventeenth-century Quakers were?

Question

a- an offshoot of the Calvinists; they insisted on an even stricter doctrine of predestination and were so named because they tended to quake with fear on their deathbeds.
b- believers in an inner “light” of grace or understanding given by God to each man and woman.
c-English yeomen who learned to grow and market oats with particular success; they were known for wearing flat, broad-brimmed hats.
d-a radical religious sect whose ministers cultivated a particularly emotional style of preaching and were so named because preachers made their listeners quake with fear and sorrow for their sins.

Answer 1

B--they believed God could fill you with his grace, which sometimes could lead to "quaking", as though you were shivering with anticipation of something good. They didn't have ministers in the usual sense, because they believed God gave understanding to all believers.

Answer 2

From the wiki;
"The various branches have widely divergent beliefs and practices, but the central concept to many Friends may be the "Inner Light" or "that of God within" each of us. Accordingly, individual Quakers may develop individual religious beliefs arising from individual conscience and revelation coming from "God within;" further, Quakers are obligated to live by such individual religious beliefs and inner revelations."

Therefore, it must be answer B.
