a. cl
b. cl
c. f
d. f

 option b.Cl

Cl represents the largest atomic radius

Explanation:

Atomic radius

It is the distance between the center of nucleus and the electrons present in the outermost orbital.

It is directly proportional to the atomic number or the mass number.

Atomic radius can also be derived from the atomic number of the chlorine and fluorine, since they are directly proportional.

Atomic no of chlorine is 17 and the atomic no of F is 9. Proportionally would be the atomic radius.

Chlorine is given by the symbol Cl.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
