problem with NFHS question #62

[shipwreck]

Here is the question with what I believe to be the correct answer, but am getting arguments from numerous umpire colleagues.

62. All the following are true regarding the FLEX player, except;
a. The FLEX is listed in the 10th position in the lineup.
b. The FLEX may be substituted for by the DP playing defense.
c. The FLEX may bat anywhere in one of the nine positions of the batting
order.
d. The FLEX may be replaced by a legal substitute at any time.
e. When the FLEX is substituted for, the team is down to nine players.

I answered e, but many around me say c is also a correct answer. I wholeheartedly disagree with them. Even the higher up person said there are two correct answers, c and e.

Is this question poorly worded for them or am I missing something? I say the Flex may bat anywhere in one of the nine positions of the batting order.( As long as the DP is listed there)

Any help here? Thanks, Dave
