What is the major product formed during the debromination of $meso-2,3-dibromobutane$?

What is the major product expected from the following reaction?
Where $D$ is an isotope of hydrogen.

The stability of $Me_2C=CH_2$ is more than that of $MeCH_2CH=CH_2$ due to

Addition of $HBr$ to propene yields $2-$bromopropane,while in the presence of benzoyl peroxide,the same reaction yields $1-$bromopropane. Explain and give the mechanism.
