  1. The following statements are related to temperature stresses developed in concrete pavement slabs with free edges (without any restraint):
    P. The temperature stresses will be zero during both day and night times if the pavement slab is considered weightless
    Q. The temperature stresses will be compressive at the bottom of the slab during night time if the self-weight of the pavement slab is considered
    R. The temperature stresses will be compressive at the bottom of the slab during day time if the self-weight of the pavement slab is considered
    The TRUE statement(s) is (are)
    1. P only
    2. Q only
    3. P and Q only
    4. P and R only
Correct Option: C
