A
stress developed in the rod is $$E\alpha \Delta T$$ and strain developed in the rod is $$\alpha \Delta T$$
B
both stress and strain developed in the rod are zero
C
stress developed in the rod is zero and strain developed in the rod is $$\alpha \Delta T$$
D
stress developed in the rod is $$E\alpha \Delta T$$ and strain developed in the rod is zero
