The correct answer is:

(b) Increase

An increase in Exhaust Gas Recirculation (EGR) can result in some cycle partial burns and, in extreme cases, total misfires. This happens because higher EGR rates can lower the oxygen content in the combustion chamber, leading to incomplete combustion and potentially misfires.
