In general, it does not matter which router becomes the route-reflector.
All route-reflector-clients will receive the BGP routes, so if it has an
EBGP neighbor it can forward the routes. I like to take the physical
topology into account when choosing a route-reflector. In this case, R1 has
direct physical links to R2, R3, and R5. So I, like the author, would
choose it as the route-reflector. I do not feel that your choosing R3,
however, violates the question.
Want to add a bit more to this question? If so, make R3-R4 and R5-R7 EBGP
neighbors. Make R3 a route-reflector (clients will be R1, R2 & R5). Also
make R1 a route-reflector (clients will be R2, R3 & R5). Be sure R2 sees
all routes. Now break the connection between R1 and R3. You know it works
if R2 can still see the routes from AS3.
