規則五薪水問題 - 美國職棒

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 a
ll or part of the season preceding the player’s selection, a Major League Clu
b that returns such a player to the Major League Club from which the player wa
s selected shall be liable for any salary set forth in its Major League Unifor
m 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 Lea
gue 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
