In the question below, a part is highlighted in bold, which may not be  grammatically correct. Choose the correct alternative for the highlighted part to make the  sentence grammatically correct. Following the rise in cross-border e-commerce, several logistics startups has emerged across Southeast Asia as low-cost delivery solutions.

Explanation:    The subject "several logistics startups" is plural, so it requires the plural auxiliary "have," not "has" — this is a classic subject-verb agreement error.    (a) incorrectly inserts "the" before "Southeast Asia" (a proper noun/region name that doesn't take an article) while still using the wrong singular verb "has."    (c) wrongly changes the verb to a continuous form ("have emerging"), which is grammatically invalid — it should be "have emerged" (present perfect), not "have emerging."   (d) incorrectly uses a passive construction ("has been emerged") — "emerge" is an intransitive verb and cannot be used in the passive voice.
