A wire of length '$$l$$' and resistance $$100 \Omega$$ is divided into 10 equal parts. The first 5 parts are connected in series while the next 5 parts are connected in parallel. The two combinations are again connected in series. The resistance of this final combination is:

A
$$26 \Omega$$
B
$$52 \Omega$$
C
$$55 \Omega$$
D
$$60 \Omega$$
