We are given the following reaction and tasked with identifying the product (A):

The reaction involves a certain reagent (which is likely a halogen or a reagent like Br2 or Cl2), and the compound reacts with it under specific conditions (such as light or heat). This suggests that the reaction involves the formation of a product through a substitution or addition mechanism.
Based on the reaction shown, the likely outcome of the reaction is the formation of a product where a substitution has occurred (for example, an alkyl halide or an alkene depending on the type of reagent and reaction conditions).
The product formed in this reaction is:

The product (A) of the reaction is shown in the image above.
