​A firm that acquires a substitute product can try to reduce inter-product cannibalization by

A) ​Doing nothing
B) Repositioning its product or the substitute so that they do not directly compete with each other
C) Pricing each product at the same level
D) ​Lowering the prices on both the products

Repositioning the products so that they do not directly compete with each other can help reduce inter-product cannibalization. This would involve identifying different target markets or unique features and benefits of each product and highlighting them in marketing messages. Doing nothing (Option A) would not address the issue and may result in continued cannibalization. Pricing each product at the same level (Option C) or lowering prices on both products (Option D) may result in reduced profits without necessarily addressing the problem of cannibalization.
