Splitting of a signal in a proton NMR spectrum tells us the number of chemically

Question

Splitting of a signal in a proton NMR spectrum tells us the number of chemically non-equivalent hydrogens in the immediate vicinity of the hydrogen giving the signal. Predict the number of lines exhibited by hydrogens at the labeled positions in a first-order NMR spectrum. (Make the approximation that all coupling constants are equal.)

The number of lines exhibited by hydrogen(s)ais.
The number of lines exhibited by hydrogen(s)bis.
The number of lines exhibited by hydrogen(s)cis.

The number of lines exhibited by hydrogen(s)ais.
The number of lines exhibited by hydrogen(s)bis.
The number of lines exhibited by hydrogen(s)cis.
