B is correct.To hee the EUR-nominateassets Björk will selling forwarcontracts on the SEK/EUR cross rate. A higher forwarpremium will result in higher roll return Björk is selling the EUR forwara higher all-in forwarrate, anclosing out the contraa lower rate (all else equal), given ththe forwarcurve is in contango.A is incorrebecause Björk is heing EUR-nominateassets with a EUR-nominateforwarcontract. While it is true ththe gbetween spot anforwarrates will higher the higher the interest rate fferentibetween countries, this g(basis) converges to zero nematurity te, when the forwarcontracts woulrolleC is incorrebecause forwarcontracts not generate premia income; writing options es.中文解析这道题目从roll yiel公式来判断。首先明确一下持有的是外币EUR的资产，因此是short forwaron SEK/EUR。此时roll yiel计算式子是F-S/S。而forwarpremium指的是F S，所以根据roll yiel公式可知，roll yiel正，即有更高的roll yiel。C指的是期权费，本题不涉及，A的基差风险本题也不涉及。
