I think option E is the best answer here.
The argument is trying to prove that Bruno was the spy.
Main evidence:
• the spy worked at the French embassy
• the spy was “the only clergyman”
• Bruno was a clergyman and worked there
But that alone is still not fully enough,
because another important thing is the timeline.
Option E directly strengthens that missing link.
If Bruno’s exact time at the embassy matches
the exact period during which the spy was transmitting information,
then the identification becomes much stronger.
So E directly supports the conclusion that Bruno was the spy.

Why the other options are weaker:
(A)
This actually weakens the argument slightly.
It says each French embassy included
at least one member of the clergy.
“At least one” means there could have been multiple clergymen,
which goes against the statement that the spy was
“the only clergyman” at the embassy.
So A does not strengthen the argument.
(B)
Being condemned by the pope later does not prove
that Bruno was an English spy.
No direct connection.
(C)
Meeting English aristocrats was normal diplomatic behavior.
That does not make someone a spy.
(D)
This only explains how Bruno got the embassy position.
It does not connect him to spying activity.
---
So option E is the strongest support because
it connects Bruno directly to the same time period
in which the spy activity occurred.
Answer = E
