Identify the FALSE statement from the following, pertaining

Identify the FALSE statement from the following, pertaining to the effects due to a temperature rise ∆T in the bar BD alone in the plane truss shown below:

1. No reactions develop at supports A and D.
2. The bar BD will be subject to a tensile force.
3. The bar AC will be subject to a compressive force
4. The bar BC will be subject to a tensile force.

Joints B & D will resist the force due to rise in temperature
∴ Bar BD will be subject to compression.
