Hello Everyone,
I have a Real time clock, some ADXl345 sensors and a multiplexer wired to my ESP32. I am using the SDA and SCL lines and not know if it Is okay to wire them physically in either of the options below. Please let me know any suggestions since this affects my wiring and programming.

You need to go for the first option for sure!
I'm even wondering how you could wire them in series since they are not an input and an output!
Why not put them all on one bus as they each have different addresses.
when the RTC has a different I2C address than your three ADXI345, but in parallel to your MUX (first drawing).
