Des avantages indéniables (incontestables?)

Question

For the phrase "undeniable advantages" I used the adjective "incontestables" and this was marked wrong.  Could I not use this word, in this context?  Thank you.

Accepted Answer

Bonjour Mary and Maarten,
You're both correct! Thanks to you, "avantages incontestables" has now been added to the list of options. However, the best option is (undeniably ;-) ) "avantages indéniables".
Alos, you might want to use "irréfutables". However, it only works with "preuve" (= proof) or with "argument" (= argument).
I hope this is helpful.
Bonne journée !
