Respuesta :

Answer:

d. all of these.

Explanation:

OTL is used in PLC programming. It is a retentive output in nature. The major function of OTL is as mentioned in the options(all of them)  itself. Given that it can only turn on a bit and cannot turn it off it is often used in pair with OTU(output unlatch) where both OTL and OTU  address the same bit.
