B. Europeans threatened violence against their families and made them choose a side - The pressures and threats from European powers often forced Native American tribes to align with one side or the other for their own safety and the protection of their communities.
C. They wanted to double cross both the French and the British - Some Native American groups played both sides against each other in order to gain strategic advantages, although this was not universally true for all tribes.
