Two identical beakers `A` and `B` contain equal volumes of two different liquids at `60^(@)C` each and left to cool down. Liquid in A has density of `8xx10^(2)kg//m^(2)` and specific heat of `2000J kg^(-1)K^(-1)` while liquid in `B` has density of `10^(3)kg m^(-3)` and specific heat of `400J kg^(-1)K^(-1)`. Which of the following best describes their temperature versus time graph schematically? (assume the emissivity of both the beakers to be the same)
