A series circuit only has one loop
true
voltage is devided only in series circuit and is the same at the parallel circuit
A circuit breaker must be reset to ON after a short circuit but does not need to be replaced. It depends on the type of CB. A fuse is also a circuit breaker and it needs to be replaced after a short circuit. Relayed circuit breakers have to be "picked up" after a dropout and need not be replaced as such.
&& and are short circuit operator in C. It means that expressions chained with these operators are only evaluated until the result is unambiguously determined. For example, the expression a && b is guaranteed to be false if a is false. In this case, the term b is not evaluated, and any possible side-effects of b will not occur. The logical OR () is implemented in a similar fashion: c d is guaranteed to be true of c evaluates to true, and d is not being evaluated in this case. The ternary ? operator is not a short circuit operator (this was listed as a short-circuit operator in a previous revision of this answer). An expression that uses the ternary operator, for example e = f ? g : h is nothing but an alternative form of an if-else construct. The terms f, g and h may each contain short-circuit operators and be evaluated in the manner discussed above, but the ternary operator itself has no short-circuit characteristic.

True!
Long winded but true.
true
True
All of the above; nothing above is true.All of the above; nothing above is true.
yes
True. The voltage rating of a fuse must be greater than the circuit voltage.

It stops flowing. An analogy to this is the kitchen faucet ... water is always "at the ready" behind the valve, ready to flow when it is enabled. Same is true in an electrical circuit - once the circuit is broken (valve closed in above analogy) the flow of electrons ceases. If there is a light bulb which is not on it is a open circuit. If the light bulb is still on it is parallel circuit which has lot of wires causes some of the lights to go on and some to go of.
