The given expression can be simplified using exponential notation as 11 x 10^aa948_cdd6_d75a_84bc_d3376161f16f_TB2342_11 mm, where the value of x will determine the final size of the pupil. When x=0 (no light), the expression becomes 11 x 10^aa948_cdd6_fe6c_84bc_87581bd2bd81_TB2342_11 mm, which is approximately 0. When x approaches infinity (infinite light), the expression becomes 11 x 10^aa948_cdd6_fe6d_84bc_a3a3be64e86a_TB2342_11 mm, which is essentially an infinitely large value compared to the other options. Thus, the best choice is A.
