The alpha decay of polonium isotope 11ea7812_82e1_ecab_bbd5_5f659c59d5ac_TB4510_11 involves the emission of a helium nucleus, which has a mass number of 4 and an atomic number of 2. Therefore, the product of the alpha decay will have a mass number that is 4 units less than the original isotope and an atomic number that is 2 units less.

The original isotope has a mass number of 208 (indicated by the digits 81 + 127) and an atomic number of 84 (indicated by the subscript 82).

The product of the alpha decay will have a mass number of (208 - 4) = 204 and an atomic number of (84 - 2) = 82.

Therefore, the correct answer is option B, which has a chemical formula of 11ea7812_82e2_13bd_bbd5_1b65dab06074_TB4510_11.
