Explanation:
Mechanical mouse has a ball that turns rollers inside. If friction is lost between the ball and the mousing surface, or between the ball and the rollers, the mouse fails to work. In order to assure good contact with the mousing surface, the ball must be fairly heavy. When you change directions with the mouse, you must make the ball change rolling directions--an action that inertia likes to prevent.
An optical mouse makes use of an LED and some optics to detect surface texture and the changes in it as the mouse is moved. There are no moving parts

I. is syntactically correct if genderString exists. if genderString, for example, is "Male", then char gender would be the character at index 0 (the first character), meaning 'M'.
II. is incorrect. It is using the comparison operator (==) instead of the assignment operator (=). It is also setting a boolean variable to a String value of 'F'. Boolean values cannot hold string values, and can only hold true & false.
III. is correct if ageString only contains numbers (presumably, it does, as it's called ageString). Integer.parseInt is a function that converts String values to integer values if the string values only contain numerical characters.
The answer in this case should be B. II only.
