Explanation

In Linux/Unix file permissions, chmod uses symbolic notation where u = user (owner), g = group, o = others, and a = all. The permission types are r (read), w (write), and x (execute). The + operator adds a permission. Therefore, chmod u+x script.sh adds execute (x) permission for the file owner (u). Option B and C use e, which is not a valid permission symbol. Option D (chmod o+x) would grant execute permission to others, not the file owner.
