The correct answer is became.
'Has become' is incorrect because we have a limited time (during the 19th century), and present perfect tense means that the action is still happening in the present. 'Becomes' is incorrect because this happened in the past. 'Had become' is incorrect because you use past perfect tense only before something else happened in the past. 'Would became' is incorrect because it should be would become.

k
=
4
