The correct answer should be the second option - Ferrite and Cementite.
A eutectoid reaction is referred to the phase transformation or change of one solid into two other different solids.
Eutectoid reaction occurs at the eutectoid point of 727°C and 0.77% Carbon, which when cooled gives α-Ferrite and Cementite, also known as Pearlite. Below the critical temperature of 723°C, austenite is no more stable and it gets converted into pearlite.
