In the Gift of the Magi, both the husband and wife sell off something important to them. Little did they know, they got the other a special gift that would go with what they sold off. So i think the answer would be B. She loves her husband enough to give him a costly gift.
Yes, it seems to be an alternative, in some situations acceptable, but eccentric and not neutral spelling of this word. It accents the fact that "ea" here are two separate vowels rather than a diphthong: that is the function of the trema (the two dots).
In practice it's not used much, because it's not really necessary: it does not distinguish it from any other word, and trema is not easy to find on English keyboards: so there is no need.
