2001 Honda Civic LX 150 K. Oil drops on driver side floor mat below accelerator. on 2001 Honda Civic

My 2001 Honda Civic LX currently have 150 K. Lately, I’ve been noticing few oil drops on driving side floor mat exactly below the accelerator paddle. While having the alternator belt replacement, I noticed an oil leak, around the bottom half of the engine but I am not sure why drops would appear inside the car on the floor mat. Please advise?

It could be brake fluid or coolant. If it is brake fluid your master cylinder and /or brake booster needs to be replaced . If the fluid is coolant there is a possible heater core .
Thank you so very much for your feedback.
