Which statement is true for a series circuit?
select one of the options below as your

a.
the voltage is the same across all resistors in the circuit.
b.
as more resistors are added, the current will decrease.
c.
the average of the voltage drops will be the total voltage in the circuit.
d.
the current is the same across all resistors in the circuit.
e.
the equivalent resistance will be greater than the individual resistors.

Each of those choices has some truth to it, but three of the five choices also include some nonsense.

A.  The voltage divides proportionally among all resistors in the circuit.

B.   As more resistors are added, the current will decrease.   True, because the total resistance will increase.

C.   The sum of the voltage drops will be the total voltage in the circuit.

D.   The current is the same through all resistors in the circuit.

E.  The equivalent resistance will be greater than the individual resistors.  True, because the equivalent resistance is the sum of the individual resistors.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
