Final answer:
The letters 'i' and 'v' have line symmetry as their halves mirror each other. 'k', 's', and 'z' do not have this symmetry, making option D) i, k, v the correct answer.
Step-by-step explanation:
The question asks which letters have symmetry with respect to a line. Symmetry in letters can be vertical, horizontal, or both, depending on how you can divide the letter by a straight line and have the resulting halves mirror each other. In the options given, the letters with symmetry would be 'i' and 'v' because you can divide them vertically down the middle and the halves would mirror each other. The letter 'k' does not have symmetry because its two halves are not mirror images. The letters 's' and 'z' also do not possess line symmetry. Therefore, the correct answer is D) i, k, v.
