Answer:
Using a one time password OTP and using a three factor authentication.
Explanation:
Social engineering is a form system and network attack, drafted by an attacker, to steal user credentials needed for accessing their accounts, to steal information.
Social engineering attacks like phishing, spear phishing, baiting and quid quo pro are used to fool users to giving out their user details.
One time password is an implied use of a password just once and a new password his generated to boost security. In a three factor authentication, OTP can be used as well as biometrics of a user which can not be giving away by a user to an attacker.

Explanation:
how much the project will cost
A combination circuit would be needed for security because if you had a strait circuit if any one of those sensors or the keypad was ripped off the circuit will now let the flow of electricity be possible but with a combination circuit it helps eliminate that problem because even if on flow path is cut off, other paths are still available <span />
Answer:
True
Explanation:
Embedded operating systems are operating systems which supports hardware which is not a computer and allows the hardware to perform its task.
An example of a device with an embedded operating system is an SD card. The operating system on the card allows the card to be readable by the computer which its is plugged to.
Other examples of hardware with embedded systems are traffic lights, digital televisions, ATMs, point of sale (POS) and digital cameras.
