The correct answer is C (left hand, right arm off-break). In cricket, batting style refers to which hand a batsman uses to hold the bat (left-handed in this case), while bowling style describes both the bowling arm (right arm) and the type of delivery (off-break, which spins from off to leg for a right-arm bowler). The other combinations either mismatch common bowling styles with the wrong arm or incorrectly pair hand dominance.
