Answer:</h2>
<h2>
Step-by-step explanation:</h2>
If resistors are in series, so the current 
is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:
is the total resistance 
. Moreover:
Therefore:
18 has more factors than all of those numbers.
1, 2, 3, 6, 9, 18 are all the factors of 18.
The second Version of the game is greater for hitting the down button because substituting any number for x, the second equation would always end up having a greater amount.
The answer to your question is b
