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.
Ohm's Law answers your question. Voltage = Current x Resistance. In a series circuit you are in effect adding resistance. If the Voltage remains constant then the answer is obvious looking at the equation above.

True!
Long winded but true.
It is true that a switch is used to open and close a circut.
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.
