What are negatively charged electrons attracted to? 

We must always keep in mind that an atom's structure may be described as follows: An atom has a nucleus, where protons and neutrons live, and electrons are located outside of the nucleus.
The smallest unit of matter is an atom. Solid, liquid, or gaseous matter can exist. An atom has a size of around 100 pm. Every atom has a nucleus, which also houses protons and neutrons, which are subatomic particles.

We must keep in mind that the atomic number of an atom or element is equal to the number of protons.
An atom is encircled by certain orbits where electrons revolving.
The atomic number of an atom or element is equal to the number of electrons.
A species of atoms with the same composition is an element.
For instance, Cl and Fe.
A particular atom has a mass that is roughly equal to its mass number, which is also known as one-twelfth of the mass of the free neutral atom of carbon-12.

Option A is erroneous because neutral species never attract negatively charged species since neutral species do not possess any charge.
The right answer is option B because protons are positively charged particles that may attract electrons, which are negatively charged, to create attractive forces.
Option C is erroneous because electrons cannot be attracted to other electrons because they both contain negative charges, creating repelling forces.
Option D) is erroneous because option B was the proper selection.

Hence option (B) is correct.
