With $10$ V dc connected at port A in the linear nonreciprocal two-port network shown below, the following were observed:

  1. $1 \: \Omega$ connected at port B draws a current of $3$ A
  2. $2.5 \: \Omega$ connected at port B draws a current of $2$ A

With $10$ V dc connected at port A, the current drawn by $7 \: \Omega$ connected at port B is

  1. $3/7$ A
  2. $5/7$ A
  3. $1$ A
  4. $9/7$ A
