B simply cannot be a contender. In the text we find the words "all human actions" but B does not strongly indicate to this assertion because a statistical evidence can give various proportions of selfish human acts to unselfish ones:
1 case: proportion of selfish human acts to unselfish ones may be 1000 to 1001, and in this case the statistical data do not to support in the original text regarding the assertion "all human actions". or
2 case: proportion of selfish human acts to unselfish ones may be 1 to 1000, and in this case one can approximate the statistical data to support the words "all human actions" in the original text.
The fact that under B it may be assumed both of the cases makes B uncertain and ambiguous. Hence, B must be repudiated.
