Ответ:
"c" is the element with the most negative electron affinity.
Explanation:
We can obtain the following information from the electron configuration:
Period: Is the level in which the differential electron is in.
Group: Is the sum of all electrons in the last level.
Knowing their ubication in the periodic table, we can classify them as metals, nonmetals or noble gases.
a. 5s² P: 5 G: IIA (2) Metal
b. 5s²5p² P: 5 G: 2 + 2 = IVA (14) Nonmetal
c. 5s²5p⁵ P: 5 G: 2 + 5 = VIIA (17) Nonmetal
d. 5s²5p⁶ P: 5 G: 2 + 6 = VIIIA (18) Noble gas
Noble metals have a low tendency to gain electrons so their electron affinity is neglectable. For elements in the same period, the electron affinity gets more negative from left to right. Therefore, "c" is the element with the most negative electron affinity.

Vanessa: Dad?
Heinz Doofenshmirtz: Oh, hi, Vanessa!
Vanessa: Dad, what are you doing?
Heinz Doofenshmirtz: Well I'll be honest I don't really understand
But I fell down this hill and I got glue on my hands
Now I got records on my fingers
Kids: Wht?
Heinz Doofenshmirtz: Records on my fingers
I got records on my fingers and I just can't stop
Kids: Don't stop
Heinz Doofenshmirtz: I can't stop I got a platypus controlling me
Kids: WHT?
Heinz Doofenshmirtz: I got a platypus controlling me
Now let me sum it up
It was a strange set of circumstances
Kids: Strange set of circumstances?
Heinz Doofenshmirtz: I fell down the hill, I got glue on my hands now I got records on my fingers
And I just can't stop
Kids: DON'T STOP DON'T STOP
Heinz Doofenshmirtz: Well I would if I was able
There's a platypus controlling me he's underneath the table
Kids: There's a platypus controlling him—WHAAAT?
Kid: Oh I get it, platypus is a metaphor for whatever is keeping you down. Like, corporations are a platypus
Kids: The government's a platypus
Your teacher is a platypus
Weird Kid: My teacher is a panda
Kids: Society's a platypus
My parents are a platypus
The media's a platypus
It's all just propaganda
Yeah, we all got a platypus controlling us
Heinz Doofenshmirtz: No just me
Kids: We all got a platypus controlling us
Heinz Doofenshmirtz: I'd stop if I was able
Kids: We all got a platypus controlling us
Heinz Doofenshmirtz: I'm not speaking metaphorically
The platypus controlling me is underneath the table
Oh wait, no, he's gone!
Heyyy! There's no platypus controlling me...
There's no platypus controlling me!
