[問題] 規則五薪水問題

小弟資質愚鈍，關於規則五薪資，看了MLB規則之後還是似懂非懂
以下節錄自mlb rule 5

If a selected player was under a Major League Uniform Player’s Contract for all or part of the season preceding the player’s selection, a Major League Club that returns such a player to the Major League Club from which the player was selected shall be liable for any salary set forth in its Major League Uniform Player’s Contract with the player in excess of the total salary the player
received (under both a Major League Uniform Player’s Contract and a Minor League Uniform Player Contract) for the previous championship season.

想請問各位大大哪個條件比較符合真實情況，或是有其他更適合的解釋。
假設C球員原本在A隊（合約為1000萬/1000萬的兩年約），並在第一年結束後的規則五選秀被B隊選走，B隊在第二年正好進行到一半的時候將C退回A隊（假設忽略waiver等過程）這兩個選項是否有較符合實際情況的？

（A)B負擔當年度一半500萬，剩餘薪水在退回A隊後由A隊負擔剩餘的500萬

(B)B負責當年度所有薪水1000萬，退回後A隊不需負擔任何薪水

在此先感謝各位大大撥冗回答這個問題
