Answer:
A.
Step-by-step explanation:
Technological substitution occurs when there's preference of one product over the other due to technological advancement available in the product.
In this case, Ebdino decided to swap the production of traditional tyres for the new tubeless tyres due to the fact that customers now prefer the tubeless tyres as shown by the increase in sales of that and the reduction/decline in the sale of the traditional tyres.
The technological substitution was important for Ebdino to remain in business.
