This is a tough one.
In A, B, and C, there are various routes to get from one end to the other end through 2 or 3 capacitors.
D is the only configuration where it's possible to get from one end to the other through only 1 of them.
I'm not totally confident, but I think D is the one that's not like the others.
1 is b because a runs 20 and b rus 102 is c
Answer:
1. Count the atoms of each element in the reactants and the products.
2. Use coefficients; place them in front of the compounds as needed.
