How did weather and climate influence historical trade patterns in the indian ocean?

a. monsoon winds made sea travel from somalia and arabia easier during certain times of year. traders took advantage of this to transport goods quickly along indian ocean trade routes.
b. the southeasterly flow of monsoon winds in july led indian traders to develop trade routes from india to indonesia and australia. as a result, maritime trade between india and australia thrived.
c. the indian ocean is frozen during several months of the year. as a result, indian ocean trade routes were unusable for a significant part of the year.
d. the exchange of southwesterly and northeasterly winds in the summer made indian ocean trade routes unsafe. this forced traders to seek alternate routes.
