csc 11ebb6d7_488f_5958_b437_ff08ec2d4fec_TB8593_11 means csc(11.5864) in radians.
Using a calculator and rounding to four decimal places, we get:
csc(11.5864) ≈ 1.0154
Therefore, the answer is choice B. Since the function is csc, which is the reciprocal of sin, we can use the inverse sine function to find the angle. 
csc(θ) = 1/sin(θ) 
1.0154 is the closest value to the reciprocal of sin(11°), which is approximately 5.954. Therefore, the answer is B.
