The associated figure shows the two types of rotate right instruction $${R_1},\,{R_2}$$ available in a microprocessor where Register is a $$8$$-bit register and $$C$$ is the carry bit. The rotate left instructions $$L1$$ and $$L2$$ are similar except that $$C$$ now links the most significant bit of Register instead of the least significant one.

The matrix $$A$$ given below is the node incidence matrix of a network. The columns correspond to braches of the network while the rows correspond to nodes. Let
$$V = {\left[ {{v_1}\,\,{v_2}....{v_6}} \right]^T}$$ denote the vector of branches voltages while
$${\rm I} = {\left[ {{i_1}\,{i_2}....{i_6}} \right]^T}$$ that of branch currents. The vector $$E = {\left[ {{e_1}\,{e_2}\,\,{e_3}\,{e_4}} \right]^T}$$ denotes the vector of node voltages relative to a common ground. $$$A = \left[ {\matrix{ 1 & 1 & 1 & 0 & 0 & 0 \cr 0 & { - 1} & 0 & { - 1} & 1 & 0 \cr { - 1} & 0 & 0 & 0 & { - 1} & { - 1} \cr 0 & 0 & { - 1} & 1 & 0 & 1 \cr } } \right]$$$

Which of the following statements is true?

A
The equations $${v_1} - {v_2} + {v_3} = 0,$$ $${v_3} + {v_4} - {v_5} = 0$$ are $$KVL$$ equations for the network for some loops
B
The equations $${v_1} - {v_3} - {v_6} = 0,\,$$ $${v_4} + {v_5} - {v_6} = 0$$ are $$KVL$$ equations for the network for some loops
C
