Expert Answer
By definition of torque 
,
where 
is position vector and 
is force .
Due to above cross product of vectors, torque and force are perpendicular to each other.
Hence the scalr product 
------------------------------------------------
Torque and angular acceleration 
are related as
...................(1)
-----------------------------------------------------
From eqn.(1) , and are parallel .
hence , 
-------------------------------------------------
Hence the answer is (4) all of the above
