I am using ESP32C3 mini 1 chip for my custom PCB and using 2 sensors LIS2DH12R and MMC5603NJ , with the combination of these three in the low power mode(deep sleep for mcu stand by for magnetometer and lower power mode for accelrometer.) I was ezpecting a current consumption around 20uA consideing i have an LDO(tps7a2133pqwdsgrq1). But it actually consumes around 240- 250uA. What might be the reason?

Usually a pullup/pulldown that leaks power. Can you show us your schematic?

yeah there were 2 pullups which were unnecessary. it is now solved thank you
