The correct way to write the underlined part of the sentence to indicate a break is option C: "the Russell's viper—found throughout the Indian subcontinent—inhabits."

Explanation:

Option A ("the Russell's—viper found throughout the Indian subcontinent, inhabits") uses a dash to indicate a break, but it is not necessary in this case. The dash implies more abrupt or unexpected information, which doesn't fit here.

Option B ("the Russell's, viper found throughout the Indian subcontinent—inhabits") uses a comma to separate the subject and verb, but it is incorrect. The comma implies that there is a missing subject, which is not the case.

Option D ("the Russell's viper found, throughout the Indian subcontinent, inhabits") uses commas around the phrase "throughout the Indian subcontinent" to indicate a break, but this is not the correct placement for commas. The phrase "found throughout the Indian subcontinent" is essential to the sentence and shouldn't be separated by commas.

Option C ("the Russell's viper—found throughout the Indian subcontinent—inhabits") correctly uses two dashes to indicate a break in the sentence. The dashes set off the nonessential phrase "found throughout the Indian subcontinent" and make it clear that it is providing extra information about the Russell's viper.
