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.
The correct answer is the last option.
In citations, longer texts (for example, novels) should be put in italics, while shorter texts (like articles and short stories) should be encased in quotation marks: "Greens Get a Boost Under the Glow of the Supermarket."
I think its c cuz that what turtles are:\
Tom's cough was chronic my dude... Lol jk, but it is chronic.
The answer would be A, a period, exclamation point, and question mark have to inside the quotation marks.
