The correct option is D Lithotomy
A lithotomy is the surgical removal of a calculus (stone) from the bladder, kidney, or urinary tract. Hence, Option D is correct. Among the rest of the options, dichotomy means a division or contrast between two things that are or are represented as being opposed or entirely different, tubectomy means surgical removal of the fallopian tubes, vasectomy means the surgical cutting and sealing of part of each vas deferens, typically as a means of sterilization. These options do not express the intended meaning, hence incorrect.
