This is a deal, like many others when it pays to listen carefully to the bidding, bearing in mind that as a pair you need to score the best possible plus score, or the lowest minus score. After South’s 1H opening West can employ an artificial bid of 2NT which conventionally shows both minor suits at least 5:5 in distribution. North has enough strength to bid 3H. Then East can review the auction; your clubs are good with 4 card support    your 4 hearts probably mark West with a singleton. You should be able to make 9 tricks thus losing 50 points against 3H which probably makes 9 tricks scoring 110 points. Even if you are two off in 4C you only lose 100 points, unless you are doubled; a double of 4C may not be a good plan in a case where there are unbalanced distributions!
