What is racemic mixture ?

Vladimir Markovnikov rule : Alkenes undergo electrophilic addition reactions. It is triggered by the acid acting as a electrophile toward t-electrons of the double bond. Markovnikov's rule states that when an unsymmetrically substituted alkene reacts with a hydrogen halide, the hydrogen atom adds to the carbon that has the greater number of hydrogen, e.g., In which of the following reactions, product is racemic mixture ?
