PLEASE ANSWER FAST.Which of the four circuits shows the best way to light up the light bulbs? Pls tell me if I got the answer right, and if not pls tell me my error and give me the right answer.

first one

coz buld have two wires and it is connected with

battery

2nd one

3rd and 4th circuits are not complete and in the 1st one wires connected to each bulb are connected to the same terminal of the battery. So there is no potential difference between the 2 ends of wire so the bulbs don't light up. For it to be correct one end of wire should be connected to positive terminal and the other one to the negative terminal

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
