A group of runes meaning a Combo. His leader skill's concept is the same as Beelzebub and of Mastema. So it's your option B correct.

For the multiplier, I assume it's :

1 group of 6 runes = x5

1 group of 5 runes = x4

1 group of 4 runes = x3

1 group of 3 runes = x2

But even if you dissolve a group of 3 / 4 / 5 runes in the first batch but for the second batch you dissolved at least 6 Earth runes or the whole board, you still get the highest multiplier, because the leader skill didn't mentioned "only the first batch will be counted".
