Three particles \( A, B \) and \( C \) are thrown from the top of a tower with the same speed. \( A \) is thrown straight up, \( B \) is thrown straight down and \( C \) is thrown horizontally. They hit the ground with speeds \( v_{A}, v_{B} \) and \( v_{C} \) respectively :
(A) \( v_{A}=v_{B}=v_{C} \)
(B) \( v_{A}v_{B}v_{C} \)
(C) \( v_{A}=v_{B}v_{C} \)
(D) \( v_{A}v_{B}=v_{C} \)
