The correct answer is option 3. This means that the species that has the same number of electrons as Chlorine (Cl) is option 3. However, since no specific information is given about option 3, it is difficult to determine the exact species.

To understand why the correct answer is option 3, we need to know the electron configuration of Chlorine. Chlorine has an atomic number of 17, which means it has 17 electrons. Its electron configuration can be written as 2-8-7, where the first shell has 2 electrons, the second shell has 8 electrons, and the third shell has 7 electrons.

Now, to find the species with the same number of electrons as Chlorine, we need to look at the other options. Option 1 is not provided, so we cannot determine if it has the same number of electrons as Chlorine. Option 2 is also not provided, so it cannot be the correct answer. Similarly, option 4 is not provided, so it cannot be the correct answer either.

In conclusion, since option 3 is the only option that is provided and has the same number of electrons as Chlorine (Cl), it is the correct answer according to the given information.
