PYR/PYL/RCAR protein subfamily is conserved among plants ranging from eudicots to mosses,  these subfamily is a receptor for ABA stress hormone. These are  showing  following characters such as;
a) PYRABACTIN RESISTANCE1 (PYR1) which shows resistance to the synthetic  sulfonamide compound pyrabactin, which mimics ABA action
b) They interact with PP2C phosphatases in an ABA-independent manner to regulate the downstream activity of serine/ threonine protein kinases of the Sucrose non-Fermenting Related Kinase2 (SnRK2) family
c) the proteins are located in both the cytosol and nucleus
d) They interact with PP2C phosphatases in an ABA-dependent manner to regulate the downstream activity of serine/ threonine protein kinases of the Sucrose non-Fermenting Related Kinase2 (SnRK2) family
Which of the following combination from the above statements is correct?
