Problems with name pronunciation?

B is most correct in English.

It is obviously not a "European" name, even less an "English" name, and thus various native speakers of English in various parts of the world would have different ideas when seeing that name written.

In Britain I might fall into the way of "Y(oo)-lee-ah-nah", as possibly a variant on the European name "Juliana" (soft "J" in Europe"). That initial "Y" in front of the "L" feels as if it carries the sound of "y" as in "you" rather than in "sky", which you seem to think of. The examples of Yvonne and Yvette (starting with "ee" sound) did not occur to me when I first saw "YL" - that combination must be rare in English.

I think is option B the correct.

I posted it on forvo for you. maybe someone there knows

A)

I've never seen this name before. But in other names beginning with 'Y' - Yvonne, Yvette, Ysolde - the 'Y' is usually pronounced 'ee'.

Ee-lee-anna

I would read it as A, but I don't know if it is correct
