What is the difference between the LM34 and the LM35 based sensors?

(a) one requires external calibration while other does not

(b) one has output voltage proportional to the Celsius scale while others have to the Fahrenheit scale

(c) one is fast other is slow

(d) all of the mentioned

I got this question in an interview for internship.

This interesting question is from Sensor Interfacing in division AVR Microcontroller of Microcontroller
