Zephyr mutex in interrupt context

Why must a Zephyr k_mutex never be locked inside an ISR?

A.k_mutex only works when the kernel is built for SMP systemsB.ISRs run with interrupts disabled until the next resetC.A mutex is owned by a thread and may block; an ISR is not a threadD.Mutex code takes too much flash to be placed in ISRs
