Question

this was an extremely sophisticated, well - thought - out operation, a former senior intelligence official told me. in this sentence, sophisticated means: lacking in strength or conviction ahead in development; complex or intricate capable of arousing disagreement of or relating to or including several cultures

Explanation:

In the context of describing an operation as "extremely sophisticated, well - thought out", "sophisticated" implies that it is advanced in development and complex. The other options do not fit the context. "Lacking in strength or conviction" is the opposite of what is described. "Capable of arousing disagreement" and "of or relating to or including several cultures" are not relevant to the description of the operation.

Answer:

B. ahead in development; complex or intricate
