Which notation represents the feedback path in closed loop system repr

1.	Which notation represents the feedback path in closed loop system representation?(a) b(t)(b) c(t)(c) e(t)(d) r(t)I had been asked this question in quiz.The origin of the question is The Design Problem topic in section Design of Control Systems
Answer» Correct option is (C) E(t) For explanation: FEEDBACK can be positive and NEGATIVE and feedback is so used to reduce the ERROR of the system by comparing the final output with the desired output and reducing the error and this error is denoted with the symbol as e(t).
