[ep37][eo] "mia sola elekto" → "mia sola opcio"

• "elekto" is "choice" in the sense of the act of choosing, or its result. See dictionaries ReVo and PIV.
• "opcio" is "choice" in the sense of an option that can be chosen. See dictionaries ReVo and PIV.

The problem Pepper mentions, isn't that she's made only one choice or that she selected only one option (thus making that option her only choice), but that she has only one option available to "choose" from for this choice (i.e., she has no actual choice), so "opcio" is the more appropriate word here, quite similarly to how "option" is a good choice (pun intended) for the English dialog of this episode.
