Saad, Normally I would say A only. That's probably the answer that would be considered correct. But I have to qualify that in real life.
I set up router r1 with RIPv1/IOS 12.1(9) just like your example (int e1 is substituted for your s1) and made sure the connected routers were able to ping.
Observed: RIP only sends/receives updates from the interface covered by the NET statement. The default route is not included in any RIP updates. And surprise - updates to e0 are generated BUT SUPPRESSED as there aren't any routes to send (the connected route doesn't need to be sent).
See below. Robert

My apologies...correction... I mis-read answer A. I don't see any correct answer. Is there a "none of the above"?
