B) Technological lockout
C) Technological substitution
D) Design iteration

A) Design competition

Explanation:

Digital watch manufacturers and manufacturers of analog watches  compete against each other because their products basically satisfy the same needs. Each one offers a very different product with its pros and cons, but even though their products are so different, they can be considered substitutes.
